Clone

The Clone tool allows you to paint one part of your image onto another. This technique can be used to remove blemishes and foreign objects, such as airplanes and power lines from an otherwise clear sky.

Clone Source

To start cloning an image, you must first define the clone source, which is the point from which pixels will be copied. This is done by holding down the Alt key and clicking where you want the clone source. This can be repeated as many times as necessary.

Drawing

After selecting the clone source, you can simply paint with the clone tool as if it were a brush. The thickness and shape can be adjusted for the desired level of precision.
