I've just started messing about with masks and I'm not sure I can do what I have in mind. One thing I'd like to do is copy the red channel, for example, edit it and then use it as a mask. I've got no-where near this yet. Is it possible? I'd also like to be able to paint on the mask with soft edges but the brush doesn't work??? I can use the pencil and blur (rubbish) or I can use dodge/burn. How else can I do this? Can I paste an image into a mask? Well I obviously can't but is it possible?
