This might be a far out and not necessarily a popular idea. But I make frame animations/GIFs in photoshop often of 15+ layers. Now when I do colour correction on a still image I almost always use channel masks on a curve layer to increase brightness and contrast etc. But as soon as I create a frame animation I have to either discard the channel mask and use a basic s-curve, which doesn't have quite the same effect; or I have to duplicate the channel masks manually and change them for each frame, which is too musch work for an amination, so I almost always forego quality to save time.
So it would be realy cool to tell a layer mask to sample the green channel and generate a new mask per animation frame.
Anybody else think this'll be useful? or is there already a way to do this that I'm just missing?
