How does automatic sensor cleaning work? Canon CMOS Image Sensor EOS Series Image Quality Benefits

In search of excellence

The sophisticated design and versatility of the EOS 5D Mark IV will suit any shooting situation.

High detail.
To complete the picture

The 30.4-megapixel CMOS image sensor produces images with high levels of detail and low noise, even in brightly lit and shaded areas. Thanks to its improved resolution, the camera captures the finest details so you can crop and capture perfect shots without sacrificing image quality.

Review shots and choose the best

Each of the 30 million pixels of the EOS 5D Mark IV is made up of two photodiodes that can be used together or separately. This technology allows you to create files in the Dual Pixel RAW (DPRAW) format. This file format contains two images captured from two slightly different angles. When processing footage with software Digital Photo Professional, the user can use the data contained in the Dual Pixel RAW file to micro-adjust the position of the sharpest zone.

Incredible low light performance

Low light performance has been improved across the full ISO range, while digital noise has been significantly reduced. Also, the maximum ISO value has been increased to ISO 32000 (expandable to ISO 102400). You can be assured of superior image quality, even in low light conditions.

The next level of image processing

Built-in lens aberration correction enhances lens performance by compensating for factors such as diffraction, distortion, and chromatic aberration to dramatically improve image quality.

Digital lens optimization

The Digital Lens Optimizer expands the correction capabilities by compensating for even more optical distortion, including the effect of the camera's optical low-pass filter. The result is optimal performance and incredible image quality.

Clarity, contrast and color

The 5D Mark IV has a number of preset white balance (AWB) modes that allow the camera to automatically assess the color temperature of an image under artificial lighting conditions. Ambience Priority is designed to preserve warm tones in artificial light to convey the ambiance of a photo, while White Priority removes most of the warm tones from incandescent light and renders neutral images whenever possible.

Transfer of the smallest details

The 5D Mark IV's high-detail picture style, Fine Detail, is designed to capture the maximum amount of detail captured by the 30.4-megapixel sensor. This setting emphasizes tone transitions and high detail.
The High Detail Picture Style has three adjustable sharpness settings, similar to the Unsharp Mask filter in Adobe Photoshop and Canon's DPP software.

Consistent accuracy

Instantly

Follow the action with the improved 61-point autofocus system, which keeps the focus on the spot even on erratic subjects. The EOS 5D Mark IV 1's 61 AF points are positioned over a wider area — 8% wider vertically in the center area and 24% wider vertically in the area around the edges — giving you more freedom in the placement of your subjects when composing.

Fast continuous focusing even in low light

With a highly sensitive AF sensor, the EOS 5D Mark IV focuses effectively even in the lowest light levels as low as EV-32. This can be improved to EV-43 when using Live View with Dual Pixel CMOS AF.

High AF accuracy even with long lenses

If you shoot sporting events or wildlife, you have to use super-telephoto lenses with teleconverters to get your subjects closer. With 61 AF points, including 21 dual cross-type AF points, precise focusing is now much easier at f / 81.

Exposure metering sensor with a resolution of 150K pixels

The EOS 5D Mark IV features a dedicated 150,000 pixel IR metering sensor for highly accurate metering. It also works in conjunction with the camera's autofocus system to detect and track colored objects and perform face recognition.

Track objects with incredible precision

The EOS 5D Mark IV features EOS iTR AF, which dramatically improves subject tracking performance. Tracking can be adjusted as needed by selecting different modes when focusing and tracking faces or other subjects.

Focus Adjustment According to Subject

Canon's AI Servo AF III features an AF algorithm that enhances the sensitivity of detecting sudden movements.
Six customizable AF modes let you choose the one that best suits your subject - you can adjust tracking sensitivity, accelerate or decelerate, and automatically switch between AF points.

High-quality shooting even in artificial lighting

AF point selection

The AF area select button on the back of the EOS 5D Mark IV allows you to change AF points without taking your eyes off the camera.

Canon has announced the Canon EOS 70D interchangeable-lens SLR digital camera for the experienced amateur photographer.

So what new has this camera brought to the camera market, how does it differ from previous Canon models and cameras from other manufacturers?

The Canon EOS 70D is the first camera to feature Dual-Pixel CMOS AF technology. Each pixel on the matrix has two photodiodes that can read information both independently of each other when using autofocus, and together when building an image.

Dual-Pixel CMOS AF technology has been designed to make focus control easier and more convenient when shooting movies, challenging the notion that digital SLR movie mode is for professionals only. Plus, the Dual-Pixel CMOS AF mechanism makes Live View shooting more convenient.

The Canon EOS 70D autofocus is compatible with EF- and EF-S-series lenses, but not all lenses support the new technology.
The following table lists the lenses that support the new AF technology:

How Canon positions its camera

You can learn more about the characteristics of the device on the website of the camera manufacturer: http://www.canon.ru/For_Home/Product_Finder/Cameras/Digital_SLR/EOS_70D/index.aspx
I will focus on the advantages of the new camera that Canon stands out for:

• The EOS 70D features a new 20.2 million pixel APS-C CMOS sensor and powerful DIGIC 5+ image processor to capture 14-bit images and fine detail. Naturalness of color reproduction is complemented by smooth transitions of halftones.
• The EOS 70D captures fast-moving subjects with 7fps full-resolution burst shooting and a high-performance 19-point cross-type AF system for high precision and responsiveness. The 19-point autofocus system migrated to the new camera from the well-known EOS 7D.
• The EOS 70D captures Full HD (1080p) movies with fast, accurate autofocus thanks to Canon's unique Dual-Pixel CMOS AF technology.
• Remote shooting from different angles thanks to the Wi-Fi module: to do this, you need to connect the EOS 70D to a computer, laptop, tablet or smartphone, and then you can control the shooting remotely. Images can be viewed and immediately sent to relatives and friends, share them on social networks.
• Even in low light conditions, the EOS 70D maintains high performance. The device offers an ISO range of up to 12800, expandable to 25600, allowing you to take handheld photos in low-light conditions without using a flash.
• The camera allows you to use intuitive on-screen touch controls to capture subjects from unexpected angles or awkward positions using the Clear View II 7.7 cm (3.0 ″) diagonal Vari-Angle capacitive touchscreen display. 3: 2 aspect ratio with 1,040,000 dots for capturing high quality Live View images, finding the best shooting angle and framing.

As we get to know the camera, we'll try to confirm or deny these Canon claims.

Comparison of the camera with its predecessors

The key difference between the Canon EOS 70D and its predecessor, the Canon EOS 60D, is the new 20.2-megapixel sensor with phase difference focusing support. The new model also has a 19-point autofocus system from the EOS 7D and support for wireless Wi-Fi networks... The case is protected from moisture and dust ingress.

There are practically no external differences between the EOS 70D and the 60D. All the same design, subject to ergonomics.

The minimal changes that could be detected are associated with an approach to modern standards Canon, regarding the camera control circuit.

• the Info and Menu buttons have moved to the upper left corner;
• delete and playback keys - closer to the control dial.

On the top of the camera body:

• The mode dial has received a slight redesign. It now rotates 360 degrees, has a creative zone, a base zone and a custom shooting mode. A lock button appeared in the center of the wheel.

Below are the layouts of the camera controls:

The case is well thought out in terms of protection against dust, splashing water and dirt.
The camera rests securely in the hand. There are anatomical protrusions for both the middle and thumb, the release button is located at a convenient angle, the material is used extremely tenacious.

The menu interface is very familiar to anyone who has worked with Canon cameras before. The same horizontal navigation through vertical lists, quite simple, but also relatively cumbersome. Added fairly large touch control icons, making it possible to use the navigation discs as little as possible. Professional photographers the possibility of full control of the camera using the buttons, blindly, is left, which is very important for them.

When sighting through the viewfinder, the screen can display basic information about shooting, additional information about shooting, a virtual horizon; by pressing the Q key, a quick menu is available: it is convenient to use the touch screen to instantly set the desired settings, of which there are not too many.

Results of practical acquaintance with the camera during test shooting

For testing purposes, I was provided with a Canon EOS 70D camera without a lens, as a result of which I used the lenses available in my personal arsenal: Canon EF 50 / 1.4 USM, Canon EF 70-300 DO IS USM, Tamron SP AF 28-75 / 2 , 8 Di LD, Sigma AF 12-24 EX DG HSM. All of these lenses are designed for full frame cameras.

Autofocus

I, like, probably, many who are reading this review now, were interested in whether the expectations associated with the new technology of the hybrid autofocus Dual-Pixel CMOS AF will be justified. Therefore, the very first test of the camera, as soon as it was in my hands, was to test the autofocus. I checked its work with all the lenses that I selected for test shooting.

Ahead of events, I must say right away that of the four lenses, only two Canon lenses, which are included in the table of compatible lenses given above, were able to use the new matrix properties associated with Dual-Pixel CMOS AF technology. The other two lenses provided focusing, using the contrast autofocus capabilities, which was immediately felt.

Based on the well-proven 19-point cross-type AF system used on the higher-end Canon EOS 7D, the focus has been on testing AF performance in Live View mode.

Considering that for two years now I have had a Sony NEX-5N mirrorless camera in my arsenal, when checking the autofocus of the Canon EOS 7D camera in Live View mode, I involuntarily compared both cameras in this indicator.

1. The first mode that I have tested is the autofocus operation when the camera is slowly turned or approached the subject, without taking pictures in normal conditions under normal lighting. The Canon EOS 7D, in my opinion, was in no way inferior to my mirrorless camera and almost constantly kept objects in focus that fell into the field of view of the camera. That is, in the video mode, it seems to me, those who want to shoot films with this camera will have no complaints. Previously, I tried Live View shooting with Canon 5D Mark II – III cameras and I remember that it did not give me pleasure: in order to focus, the lens began to fidget back and forth, making a noticeable noise, and it took a lot of patience to wait for the result. Everything was comfortable here. The lens confidently kept the object in focus, which changed the distance to the camera, while everything happened almost silently and smoothly.

2. The second thing I checked was taking pictures under normal conditions with normal lighting. Focusing was almost instantaneous, both when the shutter button was pressed and when the touchscreen was touched with a finger, only in the second case the camera was already focusing exactly on the point that was marked by contact, which is often very convenient. At the same time, if the camera in automatic mode selected another object before touching, according to the program algorithm, for example, located in the center, then after touching the screen, for example, from some edge, there was a smooth readjustment of the sharpness with the subsequent release of the shutter.

3. The most interesting test was the autofocus operation in a dark room with diffused light, in which a light object was located against a light wall. At first I tried to shoot this subject in normal DSLR mode, but it didn't work. Even with the 19-point cross-type AF system, the camera struggled for a long time to focus, but in the end it gave up. But in the Live View mode, the unexpected happened: the camera seamlessly captured the object almost immediately, without making a single unnecessary movement. At the same time, in the conditions that I created, my mirrorless camera, which has only contrast focusing, also refused to focus on sharpness. It seems to me that the coherence of both the new autofocus system using Dual-Pixel CMOS AF technology and the standard contrast autofocus system worked here, which, by the way, could not autofocus with a lens that was not included in the list of compatible ones.

Based on the practical tests that I described above, I can say that the new AF system using Dual-Pixel CMOS AF technology has passed the test with flying colors even in the rather difficult lighting conditions I created: when the main AF system refused to work, the new system provided aiming sharpness. We can say that at last Canon cameras began to possess the ability to provide AF with an acceptable speed in Live View mode; this will be highly appreciated by those who like to shoot in the viewing mode on the display, and, of course, video amateurs, who often turn off autofocus during video shooting and manually focus on the focus.

High ISO

Usually, when I get my hands on a camera, the second thing I examine after evaluating autofocus speed is how the camera performs at high ISOs.

To be honest, before the camera got to me, this moment bothered me quite a lot. Here is a site where I often look at matrix test results:

The test results were not encouraging for me:

I compared the tested device with those with which I filmed last years and saw that he was ranked last in tests:

Of course, I understood that the Canon EOS 70D matrix has the smallest pixels in area, but there was a hope that new technologies would change a lot.

But the very first results of filming slightly changed my idea of ​​the camera in this test for the better.
From the practice of shooting with my cameras, I clearly determined for myself that in terms of shooting capabilities at high ISO:

1.The Canon EOS 5D Mark II is capable of shooting where I can print exhibition format pictures up to ISO 6400 (theater photography). Above it is already difficult to deal with noise, detail drops and colors float.

2. Sony camera The NEX-5N provides shooting where I can print exhibition format pictures up to ISO 3200 (theater photography). Above, at ISO 6400, it is more difficult to deal with noise, detail drops even higher and colors float.

The Canon EOS 70D surprised me in this respect.
Almost up to the sensitivity of 12800, the color remained stable and only at 12800 it swam a little.

Here are test shots taken using a Canon 50 / 1.4 lens at a constant f / 4.0 aperture:

The results of the analysis of the above test images allow us to draw the following conclusions:
1. Fully working can be considered the ISO range of 100–3200, which allows, with appropriate processing, to print exhibition format photographs.
2. The threshold value can be considered ISO 6400, although under certain conditions and content of the picture and with this sensitivity, it is possible to print photographs of exhibition format.
3. Even at ISO 12800, you can take pictures for displaying on the Internet and printing small size if necessary, but you will need a more serious approach to noise reduction when converting.

Below I will give a few pictures taken at high sensitivity with different lenses:

Soligor 19-35 (35mm), ISO 5000, 1/125, f4.5, RAW, in-camera noise reduction disabled, while converting Noise reduction options Luminance - 0, Chroma - 25.

Soligor 19-35 (35mm), ISO 8000, 1/125, f4.5, RAW, in-camera noise reduction disabled, while converting Noise reduction options Luminance - 0, chroma - 25.

Tamron 28-75 (70mm), ISO 4000, 1/125, f2.8, RAW, in-camera noise reduction disabled, while converting Noise reduction options Luminance - 0, Chroma - 25.

Tamron 28-75 (70mm), ISO 2500, 1/125, f2.8, RAW, in-camera noise reduction disabled, while converting Noise reduction options Luminance - 0, Chroma - 25.

Canon 50, ISO 1250, 1/125, f1.6, RAW, in-camera noise reduction disabled, while converting Noise reduction options Luminance - 0, Chroma - 25.

Evaluating the metrics considered in the DXOMARK tests, such as dynamic range and color depth, requires a good laboratory with a calibrated monitor and studio lighting; Considering that test shooting at home does not even allow you to come close to the level of a professional DXOMARK laboratory, I will just give a few test shots and express my attitude to the results given in the tests.

It seems to me that in terms of Dynamic Range and Color Depth, the 70D is inferior to my cameras. Here my impressions coincide with the DXO benchmarks.

Conclusions: The camera is good. A significant step forward has been made compared to the Canon EOS 60D, in many respects it is very close to the camera of the higher price range Canon EOS 7D, and in some ways it surpassed it. I'm talking about the new dual pixel CMOS autofocus technology, which will especially appeal to those who are not indifferent to video.

Specifications

My Canon 5D MKIII DSLR often performs sensor cleaning on power outages, and sometimes I go through the menu and specifically trigger sensor cleaning when I shoot in an unusual way. dangerous conditions such as caves. But other than the weird noise I hear and the mirror clicking up and down, I really have no idea how it works on what it does.

How effective is it compared to using a blower (or any alternative methods)?

Does “over-cleaning” (manual cleaning of the sensor many times) harm the sensor / mechanics in general?

How does the sensor actually remove dust?

What happens to the removed dust?

What's the most efficient and safest way to clean a sensor?

Answers

Michael Clarke

You asked a few different questions, so here goes:

1. How effective is it? It is much more effective on cameras that have it than those that don't. Not trying to be smart, but most manufacturers have implemented automatic self-cleaning systems, and complaints about dusty sensors have dropped by orders of magnitude. See Labnath's answer to this question. To learn how to use it effectively, see this question.
2. Compared to a blower? It depends on the type of dust or other substance. Ordinary dust is fairly easy to remove. The problem with blowers is that they often introduce more dust into the system than they remove. Always use a blower with a filtered inlet valve that is located opposite the outlet. Otherwise, you just sweep the dust back and forth. Dust that has been wet is slightly heavier because it causes the dust to adhere more firmly to the surface it falls on. Other substances, such as lubricants used inside the camera body, may be dirty dirt that cannot be removed by the automatic cleaning system or blower.
3. Can you overuse the automatic dust extraction system and damage the sensor / mechanical parts? With any mechanical device, wear will over time be sufficient to cause it to fail. But if there was a problem with automatic dust cleaning programs causing damage to cameras, we would have heard about it by now. They have been fairly widespread for about half a century. They can be assumed to last longer than other parts, in particular the shutter mechanism, which is usually the first inner part to wear out.
4. How it works? Most systems use piezoelectric ultrasonic vibration of an IR cut filter in front of the sensor. They vibrate at 35-50K Hz. Olympus invented it, but now Leica, Panasonic, Canon and Nikon use similar systems. Other manufacturers use a displacement sensor. The sensor itself is shaken at a frequency of about 100 Hz, but the stroke length is much longer. Konica Minolta designed it. Sony and Pentax are now using this method. Both systems usually contain a negatively charged coating, like most dust. This makes them repel each other.
5. What happens to the dust? When vibrating from the IR filter, it should fall to the bottom of the sensor, where the dust collector collects it. We believe that dust is not affected by gravity, but this is an erroneous assumption. The dust will fall if the force of the air currents around it does not create more frictional force than gravity, if the electric charge does not affect the dust stronger than gravity, or if the combination of air and static charge is stronger than gravity, Air molecules that are affected by Brownian motion, much less dust particles. There is no source of moving air inside the mirror box that could trap dust in the air for any length of time. Some designs actually use air movement to help the dust move towards the trap under the sensor. They generate this very weak air movement thanks to the designed shape of the moving parts in the dust cleaning system.
6. What's the most efficient and safest way to clean a sensor? There is none. There are more effective methods and there are safer methods. As a rule, they are inversely proportional to each other. Methods, in descending order from minimum to maximum risk factor: automatic system dust removal, blower (with filtered air inlet), electrically charged brush and wet cleaning systems that use swabs and cleaning fluid.

Michael Clarke

Every other part of this question is also covered elsewhere on this site, but not all in the same place. What's wrong with keeping all the information in one place, rather than distributing it across multiple issues?

mattdm

Well, this part seemed to be very different from the rest when it comes to automatic cleaning. I AM really I think it’s better to ignore.

mattdm

A plus, this is a huge topic in itself.

Michael Clarke

@ user152435 Please read this part of the answer even more carefully. Some(hint: not all) manufacturers use "... piezocrystalline ultrasonic vibration ..." Other use a method that moves the sensor at a frequency of about 100 Hz. What type of camera is used?

Alex Volpe

The automatic sensor cleaning function is barely effective, especially when compared to manual methods. A filtered blower or even dry compressed air works if they do not introduce moisture into the chamber. Wet cleaners can be effective, but because they are wet they can stain and, depending on the chemical, can even damage your low pass filter / sensor, and since the LPF is a separate piece of glass from the sensor, chemicals can get in, leaving streaks and spots in all places that you cannot reach without complete destruction.

Hugo

Please provide any reliable source that automatic sensor cleaning is barely effective compared to manual methods. The answers to this question (photo.stackexchange.com/questions/10720/...) seem to contradict the inefficiencies of these systems.

Hugo

I know how it works, but I just don't find anecdotal evidence of the possible (in) effectiveness of automatic dust removal as an answer here. Also, using compressed air as you suggest here can seriously damage the sensor.

And working in conjunction with the original DIGIC processors, the CMOS image sensor is equipped with an advanced noise reduction circuitry at every pixel, resulting in images with virtually zero noise. Compared to

With CCD technology, CMOS image sensors are less energy efficient, resulting in increased battery life.

Canon CMOS sensors convert the signal to separate amplifiers at each pixel. Thus, unnecessary steps in the charge transfer process can be avoided and the time for signal transmission to the image processor is accelerated. This allows you to reduce noise, limit power consumption and increase shooting speed.

The image data captured by the CMOS image sensor is processed by a DIGIC processor before being written to the memory card. DIGIC technology uses advanced image processing algorithms for natural colors, excellent tonal gradation, accurate white balance and advanced noise reduction. The ultra-fast processing speed ensures that the camera responds quickly and turns on almost instantly.

DIGIC processors work with a high-speed image buffer - they read, process, compress and write data fast enough to keep the buffer free during continuous continuous shooting. In addition, power consumption is kept to a minimum as the DIGIC processor handles all basic processing functions.

IFCL exposure metering system with 63-zone dual-layer sensor

The iFCL system uses focus, chroma, and luminance data to continuously control exposure. All focus points provide distance data to the metering system to determine the distance to the subject and calculate an accurate exposure.

Both the EOS 600D and EOS 1100D have a 63-zone metering sensor linked to all nine AF points. Typically, measurement sensors are more sensitive to red objects, which can cause overexposure. The EOS 600D and EOS 1100D overcomes this problem with a dual-layer sensor, in which one layer responds to red and green colors and the other for blue and green. The algorithm for calculating the exposure, taking into account the data on the color of the object, corrects the readings of the exposure meter.

EOS Integrated Cleaning System

The new EOS 600D features EOS's built-in cleaning system that fights dust on the sensor in three ways: by preventing, repelling, and eliminating dust.

• Dust Prevention: The interior of the camera is designed to minimize the generation of dust. The camera body is designed to keep out dust while wearing it.
• Dust repellent: The low pass filter in front of the image sensor is made with anti-static material to repel dust.
• Dust Elimination: The self-cleaning image sensor uses high frequency vibrations to shake off dust from infrared filter for about one second after each switch-on. To instantly start shooting after activating the camera, this feature is immediately disabled when the shutter is released.

The front surface of the EOS 1100D's low-pass filter is coated with fluorine to prevent dust from adhering to the sensor. The EOS 600D and EOS 1100D have an internal Dust Delete Data system that detects the position of visible dust particles on the sensor. After shooting, traces of this dust can be automatically removed from the image using latest version Digital Photo Professional software.

Variable Angle Clear View LCD (EOS 600D only)

The EOS 600D has a 7.7 cm (3.0-inch) 3: 2 Vari-Angle Clear View LCD screen with approximately 1.04 million dots. It provides high quality display and focus check capability in playback mode. With a 160є wide viewing angle, images on the Clear View LCD are highly visible in a variety of conditions, while ghosting and flare are reduced with triple anti-glare coating and a smudge-resistant fluorine coating. In addition, screen marks are prevented and colors appear natural on the display and are consistent with the sRGB color space. The variable-angle screen opens to the side, allowing photographers to shoot from unexpected angles, even when the EOS 600D is mounted on a tripod or vertical grip. The screen can be tilted 175 °, after which it can be rotated 90 ° forward or 180 ° backward. Thus, photographers can view the display from low or high points or even from the front of the camera.

EOS Movie function

The EOS Movie function allows you to record Full HD (1920x1080p) movies on the EOS 600D and HD (1280x720p) movies on the EOS 1100D. The EOS 600D supports fully manual exposure control and frame rates of 30fps, 25fps, and 24fps at full resolution, as well as 60 and 50fps at 720p. The EOS 1100D is available at 30fps or 25fps.

When shooting Full HD video with the EOS 600D, you can use a dedicated Movie Digital Zoom to magnify the center area of ​​the sensor 3-10x while maintaining Full HD quality.

EOS Scene Recognition Technology (EOS 600D only)

EOS Scene Recognition technology automatically analyzes faces, brightness, motion, contrast and distance. This information is used in Scene Intelligent Auto.

Intelligent Auto Scene Detection (EOS 600D only)

Scene Intelligent Auto uses the information gathered by EOS Scene Recognition to select optimal settings. For example, for portraits, settings are selected that reproduce natural-looking skin tones.

Picture Styles

The preset Picture Styles can be compared to different types of film with different sensitivity to color. Within each of them, you can adjust the sharpness, contrast, tone and color saturation. The Standard Picture Style allows you to quickly produce ready-to-use JPEG images without the need for additional processing. When shooting in RAW format, Picture Style settings can be changed using Canon's Digital Photo Professional software.

The following preset styles are available on the EOS 600D and EOS 1100D.

• Standard: For crisp, vivid images that do not require post-processing.
• Portrait: Optimizes color tone and saturation, and reduces image sharpness for pleasing skin tones.
• Landscape: Increases the saturation of the greens, blues, and sharpness for sharper outlines of mountains, trees, and buildings.
• Neutral colors: ideal for post-processing.
• Precise Color: Adjusts the color to match the subject exactly when shooting in color temperatures below 5200 K.
• Monochrome: Suitable for monochrome photography using a variety of filters (yellow, orange, red, and green) and toning (sepia, blue, purple, and green).

The EOS 600D has a new feature called Picture Style Auto. It makes fine adjustments based on the analysis performed by EOS Scene Recognition to create a style for a specific picture. Three custom Picture Styles can be applied to save settings created with the supplied Picture Style Editor software, or any Styles that can be downloaded from the Canon website: www.canon.co.jp/Imaging/picturestyle/file/index. htm.

Basic +

Basic + is a creative feature first introduced with the EOS 60D. It serves to create the desired effects when shooting a scene. With Basic +, photographers can bring their ideas to life using a scene-appropriate mode.

• Shoot according to ambience: Adjusts exposure compensation and white balance according to a preset style to convey the atmosphere or tone of the image
• Shooting According to Lighting or Scene Type: A simplified form of white balance adjustment that allows newcomers to the field digital photography change settings, focusing on more understandable terms such as "daylight", "shade", "cloudy", "sunset", "incandescent lamp", "fluorescent lamp"

Automatic Lighting Optimizer (ALO)

The Automatic Lighting Optimizer analyzes the image and selectively adjusts the brightness for clearer images. For example, when a person is backlit, ALO recognizes the face and brightens it up.

Lens Peripheral Illumination Correction

Lens Peripheral Illumination Correction uses the power of the DIGIC 4 processor to enhance image quality by maintaining uniform lighting across the frame, even when shooting with a wide aperture zoom lens. When recording in RAW format, an even stronger correction is available using

Digital Photo Professional software.

Light shade priority function

Highlight Tone Priority enhances the dynamic range of light tones. The gradation between 18 percent grayscale (standard exposure) and highlights is improved, and loss of detail in highlights is reduced. Thus, an image with many light shades (for example, a photograph of a brightly lit bride in a wedding dress) looks more attractive, natural, with good detail in the white and gray areas.

Feature Guide

The built-in function guide provides simple descriptions of all modes and functions on the operating screen.

Art filters (EOS 600D only)

The EOS 600D features a range of artistic filters that let you modify RAW and JPEG images. Since filters are used after the photo is taken, different effects can be applied to the same image.

• The effect " fish eye»: Reproduces barrel distortion of a similar lens. The effect can be adjusted. Depending on the level of distortion, the outer edges of the image may be cropped.
• Grainy Black & White: Creates grainy black and white images. This effect can be enhanced by adjusting the contrast.
• Soft Focus: Provides soft focus. The effect is enhanced by adjusting the blur.
• Toy Camera Effect: Lets you achieve the colors typical of toy cameras. The image is also darkened at the four corners. The photo looks a little blurry and slightly grainy. You can choose warm or cold shades.
• Miniature Effect: Apply to sharpen a portion of an image. The orientation (vertical or horizontal) can be changed by pressing the INFO button.

Video insert (EOS 600D only)

The video insert function allows you to shoot short video clips of 2, 4 or 8 seconds. These short snippets are then combined into a single cutscene album format to create dynamic, fast sequences. After selecting the length of the video clip, each time you press the video button, a video of the specified length will be recorded. For example, if a 4-second cinematic is selected, an album of cutscenes is created from 4-second clips. This ensures you get a more immersive movie and the ability to analyze the resulting frames.

You can add background music when playing videos, cut-in albums, or slideshows on your camera screen or on a larger HDTV screen (via HDMI). To do this, the audio files [i] must be converted to a supported WAV format and then loaded onto the camera's SD card using EOS Utility. The downloaded files can be selected during playback. Also, users have access to five music tracks included with the camera.

Digital Photo Professional Software

Digital Photo Professional (DPP) software is designed for high-speed, high-quality processing of lossless RAW images. It allows you to instantly see the results of your changes, giving you full control over the parameters of RAW files: white balance, dynamic range, exposure compensation, noise reduction and color tone. In addition, it is possible to view the AF points in the image and apply the Unsharp Mask filter. Lens aberration correction tool for precise correction different types distortion in certain lenses. Added the ability to correct distortion for the EF 8-15mm f / 4L USM Fisheye. This allows you to create fisheye images for a variety of purposes.

• Linearity Emphasis: Converts the image to a central projection. Captures a full-frame image from a circular fisheye image.
• Distance Emphasis: Converts an image to an equirectangular projection. This method maintains the distance between objects, but removes most of the distortion. It is especially useful for creating star maps and diagrams of solar orbits.
• Periphery Emphasis: Converts an image to a stereographic projection. It is intended for correct display of relative positions on a spherical surface (for example, an image of the globe).
• Center Emphasis: Converts the image to an orthographic projection, increasing the center. Useful for urban planners who measure the amount of illumination of an area across the sky to plan appropriate lighting means.

Pictures can be saved in sRGB or Adobe RGB color space. Images can also be rotated and cropped, which allows you to adjust the edges of the image and the horizon line during the processing of RAW files. Digital Photo Professional supports the picture rating system used on the EOS 600D and EOS 1100D, and allows you to assign or change the star rating for easy sorting of images.

Digital Photo Professional supports sRGB, Adobe RGB, ColorMatch RGB, Apple RGB, and Wide Gamut RGB color spaces. ICC (International Image Processing Tools Consortium) profiles can be applied to TIFF or JPEG images when converted from RAW. This ensures accurate color reproduction in programs that support ICC profiles, such as Adobe Photoshop. Image adjustments can be saved and then applied to other images, which can also help improve work efficiency.

EOS Utility

The latest version of EOS Utility adds support for remote Live View shooting (with the ability to overlay an image to align subsequent shots during studio shooting), camera settings, and image transfer. EOS Utility, which is integrated with Digital Photo Professional, can be configured to take control of Hot Folders to automatically rename and move transferred images into a structured file system. It is also possible to add EXIF ​​data to each image, including copyright information. New opportunity is background music registration: users can now add and delete WAV format files in the camera playlist1.

Picture style editor

The Picture Style Editor allows you to customize Picture Style settings to suit the needs of photographers. Each Picture Style contains detailed information on the use of specific colors. Once a new style has been created, it can be directly loaded into the camera and applied to JPEG or RAW images. When working with RAW files in DPP, you can make changes to both Personal and Preset Styles.

ZoomBrowser EX (PC) / ImageBrowser (MAC)

ZoomBrowser EX / ImageBrowser software is designed for faster and easier image management. Basic JPEG editing allows you to change the brightness and color balance of images. You can launch DPP software to edit RAW images from within the software. Users can instantly select, rename, and resize images. Plus, you can star ratings and organize footage by shooting date, making it easy to manage large image libraries. Photographers can also select, annotate and print images using a range of simplified printing options.

ZoomBrowser EX / ImageBrowser supports video editing with the new Video Snapshot Edit Task, making it easy to manage, edit and share cinematic albums.

Video Snapshot Edit Task

This feature allows you to edit cutscene albums on your computer. Individual cutscenes can be deleted or arranged in a different order, and background music can be added to them. The finished file can be uploaded quickly and easily to YouTube using a new upload job.

Canon EOS 70D SLR is the seventh digital model SLR cameras EOS Series XXD. This family of devices is mainly aimed at the more demanding amateur photographers and has always enjoyed considerable popularity. It is worth noting that with the announcement of the 60D, this series has undergone some changes, namely, it has acquired a more amateur character.

The Canon EOS 60D was announced three years ago, so it's no surprise that its successor to the 70D has been awaited for a long time, and there have been a lot of rumors ahead of the new model. We have to admit that it was a worthwhile wait. The new EOS camera can be safely considered a significant step forward from its predecessor. Compared to the 60D, there are quite a few changes. Most importantly, this is a truly new APS-C format sensor, not an upgrade to the 18MP sensor that has been appearing in subsequent EOS models since 2009 with the launch of the 7D, as well as the EOS M mirrorless camera.

In the new sensor, not only has the number of pixels changed from 18 to 20 million, but a new technology has appeared, which is dubbed Dual Pixel CMOS - each pixel consists of two photodiodes that can work independently or together. This technology improves autofocus speed in Live Wiev mode and when shooting video.

Canon EOS 70D specifications can be viewed.

Build quality and functionality.

In terms of design and workmanship, the EOS 70D resembles its predecessor. According to the specification, the housing contains the following materials: aluminum, polycarbonate resin and fiberglass. Aluminum is probably used in the inner skeleton of the camera because none of the main outer parts of the body are made of metal. Upon first contact with the camera, it seems that the plastic has remained the same as that of its predecessor, however, upon closer inspection, you can see that the quality has improved.

The individual body parts are well built and the whole structure is quite rigid. It should be noted that the overall impression of ruggedness is not as positive as with the magnesium case of the old 50D. It should also be noted that the manufacturer boasts protection in the 70D from moisture and dust, but our observations raise some doubts in this regard. Although the slots are sealed with rubber plugs, and the battery compartment closing valve has a rubber ring, the memory card slot does not have a rubber gasket, which should protect against harsh external conditions.

In terms of the size of the new EOS, it turns out to be smaller than the 60D. But the difference is negligible. The weight has not changed, the same 675 grams (body only).

Battery and connectors

The Canon 70D uses the same 1800mAh battery as its predecessor, the LP-E6. Charging the battery using the supplied LC-E6 takes approximately 2.5 hours. A fully charged battery has a capacity of approximately 920 photos according to camera specifications when shooting with the viewfinder (data based on operation at room temperature).

When testing the camera with a full battery charge, we were able to take over 1,300 shots. The BG-E14 Battery Grip can be connected to the camera, making it possible to use two LP-E6 batteries or six AA batteries. The optional AC Adapter ACK-E6 must be purchased to power the camera continuously.

The new EOS, like its predecessor, works with SD, SDHC and SDXC memory cards. The memory card slot is located on the right side of the camera behind a plastic flap.

Canon 70D has the following connectors:

• Connecting an external stereo microphone (minijack)
• Remote control connection RS-60E3,
• HDMI type C,
• USB port with A / V function

The connectors are located on the left side of the camera in two columns, each column protected by a separate rubber plug.

Control elements

In terms of handling, the 70D has undergone some changes over the previous model. Most of them relate to the back of the camera and have more to do with changing the location of the buttons. Let's take a close look at what exactly is now available to us in the new EOS. We start from the top of the camera.

On the left side we find the camera mode switch:

• P- Programmed auto exposure
• Tv- Shutter Priority AE
• Av- Aperture priority auto exposure
• M- Manual shooting (Photo and Video)
• B- Long exposure
• C- Custom
• SCN- Special Scenes (Portrait, Landscape, Close-up, Sports, Night Portrait, Handheld Night Scene, HDR Backlight Control)
• CA- Creative auto mode,
• No flash
• Scene Intelligent Auto (Photo & Video)

There is a lock button on the mode wheel to prevent accidental switching. There is a power switch under the wheel.

On the right side, we see a monochrome LCD screen with five buttons directly above it. They are basically the same as on the 60D: autofocus, shutter modes ( DRIVE), ISO, exposure metering mode, monochrome LCD backlight. Directly on the grip of the camera are the traditional shutter buttons and a command dial. Unlike the 60D, the new model has an additional button in the immediate vicinity of the control dial, which is responsible for selecting the AF area.

Now let's move on to looking at the back of the camera.

Here we can see more changes compared to its predecessor. Buttons appeared in the upper left corner MENU and INFO... The latter is mainly used to change the display of information on the main LCD screen. In this place, on the 60D, there is a button for deleting images, which in the new model has been moved under the control ring, next to the lock lever (on the 60D this element is in the form of a button). Since the lock switch is now a lever, it takes up more space and the play button is now positioned above the ring where the INFO button was previously. The Q button has moved to the upper right corner of the display. Recall that in the EOS system, this button activates the function of quick access control settings through the screen. Last modified concerns the button for starting Live View and starting video shooting, the same solution in 7D, 5D MkIII and 6D, the START / STOP button activates the mode, and around the button is the Live View / Video mode selection ring

Three buttons remain unchanged: AF point selection (image enlargement), AE lock (image reduction) and AF activation. As with the 60D, the inner control ring has an 8 position switch. The control ring is used to alter exposure, to navigate camera menus, or to change any other setting.

Like the 60D, there are buttons on the front to open the camera flash and lock the lens. The depth-of-field preview button is located on the right side of the lens mount.

Displays and viewfinder

The Canon 70D has a 3-inch LCD touchscreen with 1,040,000 dots and 170-degree viewing angles. We do not have a direct comparison with the 60D display, however we can say that the display has a very good quality... The brightness of the screen can be set using a 7-point scale. The anti-reflective coating does its job well and enhances the comfort level when shooting in bright sunlight. As with the 60D, the display has a swivel joint and is repositionable (tilted 180 degrees to the side and swiveled 270 degrees). When shooting with the viewfinder, the main LCD can be used to display various information or change operating parameters. Pressing the button again INFO brings up the camera settings screen, electronic level indicator and the shooting settings control panel. It is worth noting that in the settings menu you can choose which information screens will be available under INFO.

The 70D, like its predecessor, has a monochrome LCD that displays the most important information about camera settings. The diagram below shows all the information that is shown on the display.

The Canon EOS 70D is equipped with a pentaprism type viewfinder with a field of view of 98%. In this respect, we have a slight improvement over the previous model, as the 60D field of view was 96%. The 70D has a viewfinder magnification of 0.95x and an exit pupil distance of approximately 22mm. Diopter adjustment can be performed from -3 to +1 diopters. The items displayed in the camera's viewfinder are shown below, the information is taken from the operating instructions.

The 70D's viewfinder makes a good impression and doesn't have any major objections for its size and brightness. It is slightly larger than the 60D and also gives the impression of being slightly brighter.

Video mode

The EOS 70D's video mode has been slightly expanded from the 60D's. When choosing shooting modes, the following options can be found in the new model:

• Full HD 1920 x 1080 (30p / 25p / 24p) IPB (about 235 Mb / min),
• Full HD 1920 x 1080 (30p / 25p / 24p) ALL-I (about 685 Mb / min),
• HD 1280 × 720 (60p / 50p) IPB (about 205 Mb / min),
• HD 1280 × 720 (60p / 50p) ALL-I (about 610 Mb / min),
• VGA 640 x 480 (30p / 25p) IPB (about 78 Mb / min).

As you can see, we can use two compression methods. The intra-frame (ALL-I) method compresses each frame individually, so that we get better quality and more flexibility when editing the movie. An inter-frame compression (IPB) technique that compresses multiple frames at the same time. The 70D can record movies in fully automatic mode and manual mode. In the case of shooting in automatic mode, it is possible to adjust the exposure compensation. In manual mode, it is possible to adjust both aperture and shutter speed and ISO during recording. Moreover, in this case, it can be useful to use the touch screen, thanks to which changing the parameters will be quiet and will not add unnecessary noise to the soundtrack of the movie. It's a shame that we don't have the ability to record movies with aperture or shutter priority.

Videos are saved in MOV format with MPEG-4AVC / H.264 codec. The manufacturer recommends using memory cards with speed class 6 or higher. Due to the limitations of the file system, the video file size cannot exceed 4 GB. The camera has a built-in stereo microphone, and it is also possible to connect an additional external microphone. During recording, the sound level can be set in manual mode on a 64-point scale, or you can let the camera do it in automatic mode. As with the more advanced EOS, the 70D has support for timecodes, which are used to synchronize video and audio across multiple devices and facilitate the subsequent editing process on a computer. The Canon 70D also has a mode that allows you to record movies consisting of short scenes of 2, 4 or 8 seconds in length.

Usage and ergonomics

Although the Canon 70D has been slightly downsized from its predecessor, the grip is quite large and the camera is comfortable to hold. Additional comfort is provided by a soft rubber coating, which is also found on the back of the camera. The buttons and switches are freely accessible, most of which are located in the right hand.

With the current arrangement of the camera control components, it is quite easy and fast to work, but it is worth noting that from the point of view of ergonomics, there may be slight inconveniences. It's a shame the buttons on the top of the camera don't have a dual function like the 50D did. In this case, we would have direct access to a large number of parameters, including white balance, which can only be adjusted in the quick menu. The quality of the LCD display, as well as the ability to tilt and rotate the screen, have a positive assessment in the ease of operation. This solution is especially useful when shooting video.

Lenses

The Canon 70D is available with the kit Canon EF-S 18-55mm f / 3.5-5.6 IS STM and the Canon EF-S 18-135mm f / 3.5-5.6 IS STM Universal Zoom. These kits are certainly good for beginner hobbyists, however, the new camera is quite advanced and may be of interest to more demanding users. Undoubtedly the lineup Canon lenses has a large selection. On the other hand, the amateur lens segment is a bit lame. To purchase a high-quality and reliable lens, you need to shell out a tidy sum of money. However, don't be limited to Canon's offerings and look to other lens manufacturers such as Sigma, Tamron and Tokina. Sigma is especially worth considering as an alternative. For example, the 18-35mm f / 1.8 DC HSM lens that was recently announced is very good and not expensive glass.

Speed

The speed of the Canon 70D has no fundamental objections. Onboard is a DIGIC 5+ processor (the same one found in the 6D and 5D Mark II), which provides enough power to run the camera smoothly and without problems. The camera is ready for use almost as soon as we turn the power switch to the ON position. Basic camera operations, navigating menus, making settings, viewing or zooming in photos are smooth and free of annoying lags. Deleting individual pictures is almost instantaneous, while normal formatting takes only a few seconds. Full formatting (which is rarely done) can take a little patience.

Burst shooting

The Canon 70D offers three burst modes. The two main modes, high-speed and low-speed continuous shooting, allow you to shoot at a maximum speed of up to 7 and up to 3 frames / sec. respectively. An additional mode is called Silent Continuous Shooting and allows you to take pictures at the same speed as low-speed continuous shooting (up to 3 frames / sec).

Cleaning the sensor

Automatic sensor cleaning can be performed automatically every time the camera is turned on and off. There is also the possibility of forced cleaning, which is launched through the camera menu. During the camera test, the automatic cleaning function was active. However, at the end of the test, we noticed a few small dust particles on the sensor, which the camera was unable to remove in automatic mode. It is worth noting that these stains can be easily removed by blowing the die with a regular blower.

Flash

The Canon 70D is equipped with a guide number 12 (ISO 100) flash. Compared to the previous model, the number has been reduced as the 60D had a leading number of 13.

Flash output adjustment can be made up to ± 3 EV in steps of 1/3 or 1/2 EV. Flash illumination matches the angle of view of a 28mm equivalent focal length lens. The minimum shutter speed at which synchronization with the built-in flash is possible is 1/250 second.

Flash settings can be found in the second tab of the shooting menu. There are functions both for the built-in flash and for the external one, while in the latter case they are activated only after connection:

• Flash on / off,
• E-TTL II (Evaluative / Average-weighted)
• Flash sync speed in Av mode:
  • Auto
  • Automatic range switching 1 / 250-1 / 60
  • 1/250 seconds (fixed).
• Built-in Flash Settings:
  • Flash Mode (E-TTL II / Manual)
  • Flash Exposure Compensation (with E-TTL II) / Flash Output (with Manual Mode)
  • First or second curtain sync mode
  • Wireless functions
• External Flash Settings
• External Flash C.Fn Setting

The following settings are available for an external flash:

• Flash mode
• Synchronization (1st curtain, 2nd curtain, high speed sync)
• Flash Exposure Bracketing
• Flash exposure compensation
• Flash Zoom (Flash Coverage Angle)
• Wireless functions

The Canon 70D, like its predecessor, has a built-in controller for remote control Speedlites.

Wi-Fi

The Canon 70D, like the full-frame 6D model, has a built-in Wi-Fi transmitter, which allows the camera to communicate wirelessly with external devices. Wi-Fi offers six operating modes:

• transfer images between cameras
• smartphone connection - for viewing images and shooting remotely,
• printing images on a Wi-Fi printer
• remote control of the camera using EOS Utility,
• send images to Canon web service
• Viewing images on a TV screen

During the test, we had the opportunity to see in practice how the smartphone works with the camera. To use this feature, you need to install the app on your EOS Remote phone. The app can be downloaded from the App Store or Google Play. The following features are available on the EOS Remote:

• Viewing images from the camera (viewing / deleting / copying to a smartphone)
• Remote shooting (the camera automatically switches to Live View mode and we see the current frame on the smartphone screen; you can view shooting information, set the basic exposure parameters, and also set the focus point with a touch of your finger on the screen)
• Setting up the EOS Remote

Although the capabilities of remote control via a smartphone are rather modest, it can be quite useful in some situations. For example, if you need to use a remote shutter release from time to time, now you don't have to spend money on remote control devices or a cable.

Autofocus

The Canon EOS 70D is equipped with TTL-CT-SIR autofocus and has 19 cross-type points. In addition, the center AF point has increased sensitivity when used with lenses of f / 2.8 or faster. The detection range for the center AF point is -0.5 to 18 EV (ISO 100, 2.8), and the rest is 0 to 18 EV. In low light conditions, the flash can fire a series of flashes to maintain focus. Autofocus can operate in the following modes:

• One Shot AF - One-shot focusing when the shutter button is pressed halfway
• AI Servo AF - continuous tracking mode
• AI Focus AF - intelligent, in which the camera automatically chooses to work in AI Servo or One Shot

In addition, the following AF area selection methods are available in all modes:

• Single AF point - manually select one of 19 available AF points
• Zone AF - manually select one of five zones
• Automatic selection of 19 AF points

The settings related to the 70D's focusing system can be found in the Custom Function menu C.Fn in a separate category. There are the following options:

• Tracking Sensitivity - Adjusts the subject focus tracking sensitivity in AI Servo AF (-2 Low / Low -1 / 0 / High +1 / High +2)
• Tracking acceleration / deceleration - adjust the sensitivity to moving objects (0 / + 1 / + 2)
• 1-shot priority AF - AF performance settings and shutter timing for first image in AI Servo AF mode (release priority, focus priority)
• 2-frame priority AF - AF performance settings and shutter timing after first frame in AI Servo AF (speed priority, focus priority)
• AF-assist lamp on (on, off, IR AF-assist beam only)
• AF search when unable to reach (continue / do not continue)
• AF-area selection mode - limiting AF mode selection (default 1 point)
• Method for selecting the AF area
• Oriented AF point - orientation linked autofocus
• Manual AF point mode selection
• Illuminated AF points when focusing - situations in which AF points are displayed in the viewfinder
• Viewfinder Illuminator (Auto, On, Off)
• AF fine tuning - common for all or separately for each lens (data for up to 40 lenses can be saved)

Exposure metering

The Canon 70D has 63-zone TTL metering at full aperture. The camera has the following measurement methods:

• Evaluative metering (linked to all AF points)
• Partial metering (covers about 7.7% of the viewfinder area in the center of the frame)
• Spot metering (Covers about 3.0% of the viewfinder area in the center of the frame)
• Center-weighted metering

Permission

The Canon EOS 70D is equipped with a 22.5 x 15mm APS-C Dual Pixel CMOS sensor. The total number of pixels is 20.9 million, of which the effective is 20,000,000. The RAW extension is CR2 and is saved as a 14-bit file with a resolution of 5472 × 3648 pixels.

You can also use mRAW and sRAW. These are scalable source files that can be edited like regular RAW files. mRAW format has a resolution of 4104 × 2736 pixels, which corresponds to 11-megapixel photography, and sRAW corresponds to a 5-megapixel image with a resolution of 2736 × 1824 pixels.

White balance

The Canon 70D offers the following White Balance (WB) modes:

• Auto (3000-7000K)
• Daylight (5200K)
• Shadow (7000K)
• Cloudy, dusk, sunset (6000K)
• Incandescent (3200K)
• Fluorescent lamps (4000K)
• Flash (Automatic setting)
• Manual (2000-10000K)
• Color temperature (2500-10000K)

Thus, we have the same set as in the previous model. White balance correction can be done in the menu. This correction will have the same effect as using commercially available color temperature conversion filters or color compensation filters. Each color is adjusted to one of nine levels. You can also set white balance bracketing in the menu in the range from -3 to +3 relative to the zero position.

JPEG image quality

The camera can save JPEG images in five sizes: L (5472 x 3648 pixels), M (3648 x 2432 pixels), S1 (2736 x 1824 pixels), S2 (1920 x 1280 pixels), and S3 (720 x 480 pixels). For the first three, there are two compression levels available for selection: low and medium. Photos in S2 and S3 sizes are saved in low compression by default.

JPEG picture style options can be changed in the Picture Style menu item (Fourth tab in the shooting menu). The following styles are available for selection: Auto, Standard, Portrait, Landscape, Natural, Faithful, Monochrome, Custom 1-3

When shooting in Live View mode, it is possible to set the aspect ratio of the JPEG image. There are four options available: 3: 2, 4: 3, 16: 9, 1: 1. It should be noted that changing the aspect ratio when working with the viewfinder is not available, all images will be saved in a 3: 2 ratio.

The Canon 70D has an ISO range of 100 to 12800 in 1 or 1/3 EV steps. There is a possibility of expanding the ISO sensitivity range up to 25600.

Canon 70D has a standard 8-point scale of sharpness (from 0 to 7). I want to warn you that with a high sharpness value, the images look unnatural. In my opinion, the best results are obtained with a value of 3; a higher value should be avoided.

Art filters

The Canon EOS 70D offers a variety of artistic filters. This function is only available when shooting in LV and can be launched from the pop-up menu. We can choose from the following filters:

• Granular B / W
• Soft focus
• Fish eye effect
• Effect Oil paints
• Effect Watercolor
• Toy camera effect
• Miniature effect

These filters are also available in preview mode and can be applied to previously taken images. Below are examples of how filters work.

Shooting HDR and multra-exposure

The Canon 70D features an HDR shooting mode that matches the capabilities of the full-frame 6D model. The camera in this mode takes three pictures with different exposure values ​​(standard exposure, underexposure, overexposure), which are then automatically combined into one. The exposure difference can be set automatically or manually. Three options are available for manual setting: ± 1 EV, ± 2 EV, ± 3 EV.

The 70D also has the ability to create multiple exposure images. As with the HDR mode, the camera has the same options as the 6D. This function allows you to shoot by combining two to nine exposures in one image.

In the settings, you can select the method of multiple exposure control:

• Addition - The exposure of each individual exposure is added cumulatively. Based on the indicator (Number of exposures), it is proposed to set negative exposure compensation.
• Averaging - Based on (Number of exposure) during multiple exposure shooting, negative exposure compensation is automatically set. When multiple exposures of the same scene are taken, the exposure of the background of the subject is automatically controlled and returned to the standard value.

Noise suppression

The Canon 70D has a five-step noise reduction scale: off, low, standard, strong, burst noise reduction (4 frames are combined into one file).

The noise processing system of the 70d looks very effective. As the intensity of the noise reduction effect is increased, the image quality is noticeably improved and this is not reflected in the details of the image. The burst noise canceling function does really well and is the best noise canceling option available.

conclusions

Recently, it happens that the manufacturer most often - especially in the segment of amateur cameras - makes new model camera, which is almost the same as in previous models. In this regard, the buyer receives exactly the same product, but must pay more money for it.

Surely this definition of improvement cannot be applied to the Canon 70D. After analyzing the specifications, you can see that there have been many changes compared to the 60D, some of which relate to very important elements of the camera. In theory, the user gets more than the 60D. But how does it work in practice? This is where opinions can be divided. Without a doubt, the 70D test shows that in important categories such as image quality, resolution, noise and tonal range, the new camera offers essentially the same performance as its predecessor. And in this respect, there is a certain disappointment. Moreover, a completely new sensor is used, an increased number of pixels compared to the old 18-megapixel sensor used for several years on the Canon SLR APS-C.

The 70D can be safely considered a step forward from the 60D. The new EOS offers an even more powerful and efficient autofocus system, better performance and faster autofocus in burst mode, playback mode and video recording. In addition, the video mode has been expanded, and a wireless Wi-Fi connection is built in, allowing the camera to communicate with external devices. Thus, improvements over the 60D are immediately noticeable.

It is necessary to say about the price of the new device. At the moment, 70D costs about 45 thousand rubles. The price, of course, is not small, especially from the point of view of the average amateur photographer. As for the Canon 60D, its cost is about 29 thousand rubles. If you opt out of a newer model, you can purchase additional lenses. It's no secret that anything new is expensive and the EOS 70D is new. It is difficult to expect a drop in the price of the new EOS in the near future.
