Channels panel

About the Channels panel

As well as being able to view an image's colour channels in isolation, you can edit any channel in isolation too. Selections can be made based on a chosen channel (e.g., Reds only) and different selections can be combined, subtracted or intersected for colour-based editing. The panel also lets you store selections as spare channels for future retrieval.

As well as the channel information for the image and any currently selected layer, you'll also see the:

Current pixel selection.
Mask alpha*.
Adjustment layer alpha*.
Live filter layer alpha*.
Any stored selections (as spare channels) for future use.

* When selected in the Layers panel.

By default, all colour channels are visible and editable.
