How does a Canon mirrorless camera meter, and how does a Canon DSLR meter

For average metering, the captured picture can be divided into multiple areas, and each area will be metered independently, and then the average metering value of the entire frame will be calculated accordingly.

For spot metering, only one point needs to be metered, and it should be noted that the point of spot metering refers to the area of 1%-5% of the framing range, which is usually in the same position as the focus of the sock stool.

And it needs to be understood that when the ambient light shot by the user is more complex, or the dark contrast is relatively strong, it is more suitable to use spot metering, such as shooting silhouettes or sunsets, if it is difficult to shoot without spot metering.

For the first key metering, the range is larger than the spot metering, generally 20%-30% of the scene, mainly according to the brightness of the picture** good Zheng range for metering, and the other areas of the picture are given average metering.

1. Observe the light meter in the viewfinder window: At the bottom of the viewfinder window of the camera, there is a scale similar to the ruler used in the student days, which is the light meter that comes with the friend's eye in the camera, and you can judge whether the metering is accurate according to this scale.

2. In real-time mode, there will also be a light meter on the screen: If you use the real-time mode (LCD screen) to frame and shoot, there is also a scale (light meter) directly below the LCD screen and the light meter under the viewfinder window is exactly the same.

3. There will also be a light meter on the shoulder screen: In some mid-to-high-end SLR cameras, there is also a small display screen on the shoulder screen of the camera, and the light meter can also be seen on the shoulder screen, which is the same as the light meter in the viewfinder window and the LCD screen.

DSLR cameras. 01 First of all, you say that your camera is set to "aperture priority", and then you need to aim the lens** at your metering target.

02 After that, you press and hold the shutter halfway and start metering. At this time, the system will give you a corresponding shutter value, so that your aperture can reach a normal ** combination.

03 Metering is also possible in the "Shutter Priority" setting. In manual mode, select the "M" setting.

04 Press and hold the shutter halfway, and then the viewfinder can see the prompt message of **. You can adjust the shutter and aperture yourself to achieve the ** value.

05 Generally speaking, the manual mode does not have to be normal**, you need to combine it with your specific requirements. Choose to be overexposed, or underexposed.

Look at the light meter at **

1. Observe the light meter in the viewfinder window:

At the bottom of the camera's viewfinder there is a scale similar to the ruler we used when we were students, which is the light meter that comes with the camera, and we can judge whether our metering is accurate or not.

2 Light meter will also appear on the screen in real-time mode:

If we shoot in live mode (LCD), there is also a scale (light meter) directly below the LCD screen, which is exactly the same as the light meter under the viewfinder window.

3. There will also be a light meter on the shoulder screen:

In some mid-to-high-end SLR cameras, in the camera's'There is also a small display on the shoulder screen, on which you can also see the light meter, which is the same as the light meter in the viewfinder and the LCD screen.

Factor 1 affecting the light meter: ISO

The lower the 1iso, the less light you get: (good image quality).

There are 3 factors that affect the change of the light meter, among which ISO has the greatest effect, when we set the ISO to the lower (e.g. ) under the same parameters, the light obtained will be darker, and the light meter will be more left (the left indicates that it is darker).

The higher the 2iso, the more light you get: (poor image quality and more noise).

And when we set the ISO to a very high level (for example) we get a lot of brightness, ** will become very bright, but the higher the ISO ** the image quality will decrease, there will be obvious noise when zooming in, and the light meter will be more to the right (the right side means brighter).

Factor 2 affecting the light meter: Shutter

1. The lower the shutter speed, the more light there is (it is easy to blur when shooting high-speed objects).

The speed of the shutter can also affect metering, and the slower the shutter speed, the more light we get, but when shooting fast moving scenes (such as dancing and running), it becomes blurry.

2. The faster the shutter, the less light there is

If the shutter speed becomes faster, less light will come in, the metering will become darker, and the cursor position of the light meter will be more to the left.

Factor 3 that affects the light meter: Aperture

1. The larger the aperture, the more light (you can get a better bokeh effect).

The larger the aperture, the more light we get, the brighter it will be, and the maximum aperture is different for different lenses, the larger the aperture, the smaller the focus range will be, and the more obvious the bokeh will be. The light meter will be on the right.

2. The smaller the aperture, the less light there is (used more often when taking group photos).

If you take some group photos, or if you need to have very clear edges, you need to use a small aperture, which will get very little light, and the light meter will be on the left.

What is the best metering?

Normal metering:

So what is the best metering? Generally speaking, no matter what the scene, as long as our light meter pointer is close to the middle, it means that your metering is relatively balanced and appropriate.

Special subjects require special metering:

Of course, if you want to shoot high** (very bright) or if you want to shoot things in a dark environment (especially dark), you don't need to adjust the cursor to the middle!

1. Reflection metering, using the camera's built-in metering blind and delayed burial function, the lens is pointed at the photographed grinding elephant, and the shutter is half pressed to obtain the metering parameters;

2. See a scale on the camera's viewfinder and LCD screen, and rely on the scale to adjust the camera's ** parameter settings. When the mark of the scale value is "0" in the middle, it means that ** is correct;

3. When marked"+1", it means that the camera's **parameter setting has exceeded the normal parameter by one stop, and the aperture should be reduced by one stop or the shutter speed should be increased by one stop.

The camera metering steps are as follows:

1. Evaluative metering, also known as average metering, is to intelligently analyze the brightness of the entire picture, and finally obtain the average brightness value for calculation. It is suitable for occasions with relatively small light, wide application, and very easy to use.

2. **Selling Sen focuses on metering, which is to metering the position of about 1 3 in the middle area of the picture, because the center composition is commonly used, and the subject is in the middle, so it is very suitable for center composition and close-up shooting.

3. Spot metering, spot metering is to metering about 3% of the area of a single point, accurate metering, can ensure that the subject is correct, even if the shooting backlight is also a good performance.

4. Automatic exposure beam mu light lock, there is an automatic **lock "*" button on the camera. Use the middle area to press the shutter metering halfway on the subject of the frame, and press the auto lock "*" button to reframe the focus shot. There is generally no mistake with this metering.
