Histogram palette with all channels displayed and statistics hidden
To view a specific channel in the histogram
If you chose the Expanded View or All Channels View of the Histogram palette, you can choose a setting from the
Channel menu. Photoshop remembers the channel setting if you switch from either Expanded View or All Channels
View back to Compact View.
• Choose an individual channel to display a histogram of the document’s individual channels, including color
channels, alpha channels, and spot channels.
• Depending on the image’s color mode, choose RGB, CMYK, or Composite to view a composite histogram of all
the channels. This is the default view when you first choose Expanded View or All Channels View.
• If the image is RGB or CMYK, choose Luminosity to display a histogram representing the luminance or intensity
values of the composite channel.
• If the image is RGB or CMYK, choose Colors to display a composite histogram of the individual color channels in
color.
In the All Channels View, choosing from the Channels menu affects only the topmost histogram in the palette.
