The Healing Tool in GIMP is a tool which you can use to fix the flaws in a photo. If used correctly, it can help you to get a better result if the original image generated by your camera is not like what you have expected. For instance, you can use Healing Tool to remove lens flare.
Or, you can also use Healing Tool to manipulate the original object of your image. For instance, you can use Healing Tool to remove facial blemishes, wrinkles or cracks of an object.
Healing Tool works by copying a certain spot/area within an image to another spots. However, the spot or area is not simply copied. The area around the flaw is assessed and reproduced before the healing process begins.
