Using the Histogram

A histogram shows the brightness distribution of an image. The horizontal axis represents brightness (dark at the left and bright at the right) and the vertical axis represents the number of pixels.

The shape of the histogram before (Dark) ←Brightness→ (Bright) and after shooting tells you

whether the brightness and contrast are correct or not, and lets you decide if you need to use EV compensation and take the picture again.
