Layer Mask Basics
A layer with a mask has two thumbnail icons. The one to the left is the image and the one
to the right is the mask. If you click on the left icon, you are working on the image. If you
click on the right icon you are working on the mask. The one that is currently active will
have brackets around each of its four corners.
So, if you intend to paint on your layer mask and you discover that you are depositing paint
on your image, back up and click on the layer mask.
Notice that the layer mask reflects both the shape and position of the image on that layer.
