I don't much like Photoshop but I do like the way the brush handles. What I mean is when you set the opacity to 10% for example, and draw around the canvas, it stays the same colour no matter what. If you lift the stylus from the tablet and then draw again, the drawn over the parts that you did before become more opaque and blank areas are drawn the same colour as before.

Is there a way to get this kind of opacity build up in Painter? I've tried everything that I can think of but just can't seem to get it working..

Sorry if I don't make sense. It's 1:20am and haven't had much sleep over the past few days so the old brain(cell) is dead atm.

Thanks.
