I want to use a layer (created from an inverted blue channel) as a mask for another layer. How do I get the information from a layer (or channel) into a mask? If I try to paste it PS just give me a new layer.
Is it possible to paint with an image rather than a color?

Thanks,
Ron

Copy the layer that you want to use as the mask to the clipboard, go to the channels palette and create a new empty alpha channel then paste in to that alpha channel. Then go back to your RGB image in the channels palette (if it switched to the alpha channel then go to Selections > Load Selection and choose the alpha channel you just created. Presto mask!

That’s cumbersome and has several extra steps. You can do it more quickly by copying the channel to the clipboard, creating a new mask for the layer (Add Mask->Reveal All), then pasting the channel into the new layer mask.

OR

Copy it (Layer or Channel)to the Clipboard, create an empty mask on the correct layer, Alt-click on the empty mask you created to display it, and Ctrl-V to Paste it in the mask.
