Which of the following is correct about the "white plus black minus" principle of exposure compensation? ()

A. White plus black minus is to overexpose the subject and make the area outside the subject whiter, darker and more realistic.

B reduce the exposure when the subject is white or there are many white elements in the picture, and increase the exposure when the subject is black or there are many black elements in the picture.

C. It is necessary to increase the exposure when shooting during the day and reduce the exposure when shooting at night.

D in aerial photography, because the subject is small, photometry is easily influenced by the background, so the methods of bright background, positive compensation, dark background and negative compensation are mainly adopted (correct answer).

Answer analysis: the mistake of option a is that the ultimate goal of exposure compensation is to make the subject get proper exposure, not overexposure; Option B is wrong, because "white plus black minus" does not mean whether the subject is white or black, but you want to make the picture brighter and whiter, you want to make the picture darker and blacker, and you want to reduce the exposure; C option is even more wrong, white plus black minus has nothing to do with shooting time; The d option is a description of the exposure compensation use scenario.
