Sorry to post another thread on the same topic, but I wasnīt sure if anyone was drilling down in the other.
I have one other sugggestion as a followup to the earlier thread. It may be a sort of dumb observation--as in I was the only one to notice this after several projects when it was obvious to everyone else:
Try blending using the same brush size you used in the painting, at least at first. I tend to use very small brush strokes, and at first tried blending with a much larger tool size, trying to hurry along. The results werenīt that great. When I set the blend tool at the same size as the brush stroke, all became much smoother. It still takes forever, but thatīs how it works--at least for me.
Another suggestion: clean your screen before starting to blend. Once, I spent 15 minutes trying to smooth out a dark spot and checked all the layers. Then I noticed it was a smudge on my monitor.
