Histograms
Histograms show the distribution of tones in the image. Brightness is
shown by the horizontal axis, the number of pixels by the vertical axis.

Optimal exposure: Pixels are distributed in an even curve
throughout the tone range.

Overexposed: Pixels are clustered on the right side of
the graph.
•

tion button to which HISTOGRAM is assigned
