I have a Wacom 4x5 Intuos, and it really does make a lot of things easier, once you get the hang of it. At first I felt like a brain-damaged person going through rehab trying to use the bloody thing, but shortly it got to be second nature. I wish I'd have gotten the bigger one, (6x8, I think), but I couldn't quite convince myself to pay the extra bucks for it(plus, my girlfriend would have killed me if she knew what I paid for it) Good luck, 'Wolf

Timefighter, You can also make a new layer, do a cloud filter on it. Reduce the opacity so you can see through to your main picutre. Then what I do is use a lasso, select where I want the dust or smoke to be. Feather the selection like 8 or 10 or however many pixels works for you. Then invert the selection and hit delete to remove all the 'smoke' except for what you selected. Mess around with opacity, and it looks pretty good. Maybe combining that with the others' ideas would look groovy.
