Choosing a Histogram View for Adjustments
When you show the Adjustments inspector or the Adjustments pane of the Inspector
HUD, a 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.
To choose a histogram view:
m
Choose a view option from the Histogram Options section of the Adjustment Action
pop-up menu.
Note: The histogram updates in real time in the Viewer and in Full Screen view, but it is
slightly delayed in the Book Layout Editor, the Webpage Editor, and the Light Table. For
more information about how to interpret a histogram, see “
