Thanks for the explanation--that was a good example. I see exactly what it
does now and I understand why I wasn't seeing any effect--I only had an
image capture with adjustment layers so there were no edges to really blend.
I'm guessing that if I had a layer mask on one of my adjustment layers and
the adjustment was very dramatic, then it might come into play, but in
general it won't do anything on the type of images I work with.
Thanks again.
Ken
