How to shoot the truest color with a SLR? (Post-processing is possible)

First of all, the white balance should be properly adjusted according to the lighting conditions, the subject and the background color (the color temperature of reflected light of different colors is different).

Secondly, the aperture should be as large as possible. F 10 for indoor shooting is too small.

Pay attention to lighting, two lights, one on the left and the other on the right, have the same light intensity, so there is a serious problem with lighting. At least pay attention to the separation of main light and auxiliary light, in addition to background light, backlight, top light, weak light and so on.

You only have two lights, which is obviously not enough. It is better to have five or more lights. If possible, it is best to prepare some lamps with different color temperatures or even different colors (red, blue, green, yellow and purple) to adjust the color temperature or even the lighting color. In addition, there should be soft umbrellas and the like.

For indoor shooting, the better film should be straight out-no need to adjust later! In the past, the white balance of film camera could not be adjusted, and it could not be PS in the later stage. Indoor photography is completely solved by photographer lighting and installing filters of different colors in front of the camera.
