I am using Canon's DPP as my raw converter and do not have CS3 as of yet. My question is how to remove unwanted parts of an image with the Stamping Tool. I follow the directions from the manual I downloaded and it seems to work--I can remove a tree branch growing out of the bird's head, it shows the corrected pic, but when I hit OK, the saved pic has not changed except that there is a stamp logo on the thumbnail. What am I doing wrong?
