Also, this page:
has a broken link. It offers a video of content aware
For a video about this process, see www.adobe.com/go/lrvid911_pse_en , but when you go to that page it's all about creating a calendar.
For something as large as a person, the healing brushes alone aren't always going to do it. You may need to add the clone stamp to cover up what's left over, or you may be better off by starting with the Recompose tool and just healing and cloning any bits that recompose can't remove. It all depends on the image.
Have no idea what I did, so don't even ask. lol Double clicked on background layer and ended up creating a clipping mask. The using spot healing brush, I was able to remove water hose by the side of the pool, like I originally intended. I finally had upgraded from PSE 7 because of content aware fill and photomerge (and other stuff lol). The only thing was I seem to have lost my background layer. No problem, was working on a test file copy. Worked pretty good though. Not just have to find out what happened to my background layer. It was locked but ????? lol
