histogram of the selected image’s luminance or color channels appears. The histogram displays a
graph of the brightness values in the image, from the blackest point to the whitest point. You can
adjust the histogram to show luminance; red, green, and blue (RGB) channels displayed together;
or separate red, green, and blue channels.

Note: The histogram updates in real time for images displayed in the Viewer and in full-screen
view, but is slightly delayed in the Book Layout Editor, the Webpage Editor, and the Light Table.
