Now you can make a highly customized print, right on your desktop, and once you make it right, you can repeat the print again and again. Cloning is the process of copying one part of a picture to another. What this tool does is grab a small piece of the image and move an exact copy directly to another place in the picture. Even if your program has no cloning tool, you can duplicate the effect by copying tiny circles in the image, then pasting them elsewhere into the problem spot. This tool is extremely valuable to correct flaws in an image from dust and scratches and is a necessity for restoring damaged photos.
Cloning also fixes visual garbage.
The subject of this photo is the young boy. At the best shooting angle, there were distractions that could not be moved. The cloning tool can remove the problems to better reveal the subject. Soft edges make the cloning blend better. Hard-edges work well when you are trying to fix an area close to a sharp edge on your subject.
