    Turning RGB channels into layers
    by Doug Nelson
    I needed to do this while experimenting on a file for another thread and found the technique was slipping from my memory and I had to look it up again. I thought I'd write it down here so I wouldn't forget.

    This technique was invented by Richard Lynch for Elements users to be able to...

    Getting some pizazz into BW coversion
    by peejayw
    I am very new to PS but love the effect of coverting a photo to BW by desaturateing it then using the history brush to paint back in colour in specific areas. Problem is, how do I make the BW part of the photo more dynamic, contrasty etc without affecting the colour part?

    by FinderBinder
    Hey All,

    In RGB mode, is it possible to apply a layer mask to a component channel in a layer, instead of affecting all three channels (RGB) at once? I'm guessing no, since every layer has only one alpha channel for transparency (A). But what about a simulation?

    copy channel and paste into new layer?
    by anderson234
    Hi all,
    Very often I ctrl+A and ctrl+C a channel, come back to layers, ctrl+V.
    Sometimes I get a NEW gray scale layer, that's what I wanted.
    But sometimes it just pastes into the current layer, make it gray scale. How come? I can not find the pattern.

    Another question:...
