Appendix

A histogram is a graph that represents the lightness of an image in terms of the

number of pixels. The vertical axis indicates the number of pixels, while the horizontal

axis indicates lightness. If the histogram appears too lopsided for some reason, you

can use EV shift to move it left or right in order to achieve better balance. Optimum

exposure can be achieved by EV shifting so the graph is as close to the center as

possible. For snapshots, you can even display individual histograms for R (red),

G (green), and B (blue).

Example Histograms

How to Use the Histogram

A histogram towards the left side results when the

overall image is dark. A histogram that is too far to

the left may result in “black out” of the dark areas

of an image.

A histogram towards the right side results when

the overall image is light. A histogram that is too

far to the right may result in “white out” of the light

areas of an image.

An overall well-balanced histogram results when

the overall image is at optimal lightness.
