Photometric methods and skills in photography

The methods and skills of photometry in photography are as follows:

1, measure light with reference object;

For photography enthusiasts, it should be understood that the reflectivity of the metering system to the measured object is 18% gray, that is to say, the reflectivity of photography metering is 18% as the reference value of exposure, and 18 degree gray means that the black component accounts for 18% in pure white, white accounts for 82%, and people's skin color.

Therefore, when shooting portraits, you can use a shading board or find a gray cardboard in front of the subject, fill the screen with a shading cloth through zooming, and then focus, so that you can basically get an accurate exposure picture when shooting.

2. Alternative photometric method;

The application of alternating photometry is mainly because we can't measure the light accurately when we are too far away from the subject, so we can choose a place close to us with the same illumination as the subject's position and then apply it to the subject's position.

3. Photometry of close-range objects;

As for the metering mode, the author has already introduced it before, so I won't introduce it in detail here. Friends who want to know can pay attention to me and then go to the home page to find an article entitled "Detailed explanation and examples of metering mode" to read for themselves. Then, for the other two metering modes except the evaluation metering mode, the metering range is small when shooting with the camera, and the metering is only in the central part of the viewfinder, so the lens can be pulled as close as possible when shooting the subject.

4. Photometry in important areas of the subject;

When shooting some scenes with too big contrast between light and dark, some detailed areas should be reserved for metering, so you should be skilled in metering when shooting. For example, if you want to shoot the sunset glow, then you should take the brighter scenes around the sky as the standard of metering, so that the quality of the photos taken will be better.

5, master the brightness range;

This method allows the photographer to accurately measure the light, and then make some details in the shadows and highlights of the picture obvious and preserved. This is mainly aimed at measuring the brightness and darkness of the subject, and then determining the appropriate exposure according to the camera tolerance.
