Layer masks are one way to give a clean surface, such as metal, a lived-in look. I often use masks because they help me to focus on the shape and form of the dirt while at the same time saving a selection of the pattern, which can always be changed later on if necessary.
Masks are fairly easy to use once you understand how they work, and they can speed up your workflow significantly. You can see them as a constant selection in which you work, and while the Lasso tool can help to do the same, the downside of it is that its selections are always fully opaque.
On the other hand, a mask is an image map in black and white that will instruct the layer to which it’s applied to only show the parts from its map that aren’t pure black. So areas of pure white will be fully shown, while grey parts will be ‘ half’ shown depending on how dark they are. Now let’s see how that knowledge can be put to use!
