About the histogram

A histogram is a graph that displays brightness along the horizontal axis (black to
white) and the amount of pixels at each brightness level on the vertical axis.
It allows you to easily check a picture's exposure.
Examples of histogram:
Properly Exposed
Dark area, mid-tone,
and bright area are bal-
anced out evenly, mak-
ing it suitable to take a
picture.
HINT When you take pictures with the flash or in dark places, the histogram is displayed in
orange because the recorded picture and the histogram do not match each other.
