How to check the histogram

A histogram is the luminance distribution that shows how many pixels of a particular brightness exist in the picture.

When the image has a high-key or low- key portion, that portion is flashed on the histogram display (Luminance limit warning).

The exposure compensation will change the histogram accordingly. The right illustration is an example.

Shooting with the exposure compensation on the positive side brightens the whole picture, making the entire histogram shift to the bright side (right side). If the exposure compensation is applied on the negative side, the histogram will shift to the other side. Both ends of the histogram show a high- key or low-key portion. It is impossible to restore these area with a computer later. Adjust the exposure if necessary and shoot again.
