horizontally, and the amount of brightness
vertically. When the graph approaches the
right side, the image is bright, but when it
approaches the left side, the image is dark,
and in this way you can judge the
exposure.

The histogram can also be displayed while
shooting (p. 196).

shown horizontally, and the amount of each
shade vertically. In this way you can judge
the color balance of an image.
