Layers are a clever and easy-to-use way to introduce elements to an image without destroying the source or main image. It works similarly to placing sheets of paper on top of each other. Each piece is a separate element of the composition, but when put together, they become the image you want the world to see.
In this how-to we will use GIMP’s layers to take a stock image, remove the subject from the image, and apply effects just to the subject, leaving the background untouched. We’ll learn how to create new layers, manage layers, and apply effects to certain parts of an image using alpha selection.
