Anyone ever notice that if you use the healing brush over an area that was already healed it starts to get pretty pixelated? If so is there a way to avoid this? I can't figure out why it does this. It seems to do it even if the sample point is smooth in texture.

A tip for the healing brush is to squash it, change the brish shape to eliptical, this way the brush is more random and does not creat such a patterned look. this may help avoid the broblem you are seeing.

Sample often, from different areas.
