Histogram
A histogram is a graph that displays
brightness along the horizontal axis (black
to white) and the number of pixels at each
brightness level on the vertical axis.
It allows you to easily check a picture's
exposure.
When the values are distributed evenly,
the exposure is proper and the
brightness is well-balanced.
When the values are concentrated on
the left, the picture is under exposed.
When the values are concentrated on
the right, the picture is over exposed.
