I used the smart brush to select just the sky. Then i duplicate selection to put it on a layer by itself. Ive gotten this to work but seem to have problems getting it to work a second time. The dancing ants are still around the section i want. Sometimes im not happy with my selection after a duplicate selection so i will update my selection slightly. At this point it does not duplicate just my selected area. I have not been able to figure out a work around. I even unselect everything, and rebrush it. I even tried restarting the app, unselecting, reselecting, inverting, etc. nothing works.
So, “duplicate selection” seems to be just “duplicate”
thanks for any help.
