[Edge Images]

I recently shot a model who had stretch marks on her stomach from pregnancy. I altered the settings to try to include her stomach as I was repairing the image. It didn't work too well. Anyway, I can't figure out what I changed, and now when I am working on photos, nothing I do seems to be altered. I've tried tried to figure out what I changed and also to see if there is somewhere I can "reset" to the original settings in place when I first installed the software. If anyone knows, I'd appreciate a hand. Thanks, Larry
