As a complete newbie in the Adobe world, this is a good example of the kind of frustration that makes me want to just go back to the less-effective tools in other software packages. I'm using a Mac.
I am trying to remove an unsightly box along a fence line. I used the clone brush and the first section I modified looks perfect. So I want to do more. But there doesn't seem to be any way to "commit" the change I made and start over. When I activate the healing brush, it goes back to the changes I made already. If I try to start a new "heal", it just moves my old one around. Help please!
