@Pixey Well, what I mean by screen, is using the layer blending mode, "screen" is one of the options when pulling up the layer blending mode on a layer. When I use overlays, or images that have black backgrounds, I open it up into paint.net, and I go to the layer that it is on, and I click on the drop down menu where it shows all of the layer blending modes, and I click screen, and usually, everything on that image that is black, will not be visible.
