Showing Picker RGB Values
While you’re dragging the pointer over the Viewer and looking for a feature to sample, you can
enable a tooltip that shows you the RGB Value of the pixel under the pointer by right-clicking
the Viewer and choosing Show Picker RGB Value to toggle this feature on and off. When you
turn this feature on, the View > Show RGB Picker Values In submenu has options for displaying
either 8- or 10-bit tristimulus values.

Curves Histograms
The Custom curves and HSL curves all show a histogram that represents the input of the
currently selected Correction node, which you can use to guide your adjustments. The
Histograms submenu of the Curves palette’s Option menu lets you choose to disable these
histograms, or to switch the histograms between showing the input or the output of the node. If
you switch to Output, the histograms will update to show you the result of your adjustments, at
the expense of seeing the image data that the curve is actually working upon.
The Custom curves show a YRGB histogram:
