Got a question here that I’ve wondered for a while.
Say I make a new image. Create a new layer, and start painting on that layer. Obviously there’s some sort of alpha mask at work at I paint, as everything on the layer below appears correctly below what I’ve painted, including different transparency levels.
Now I’d like to save the image out as just what I’ve painted on that second layer, with an alpha of that layer included. So far the only way I’ve heard to do this is select the layer and then make a mask from selection, but this seems messy and doesn’t include different levels of opacity I might have working in the layer. Is there a clean way to export the painted layer with the alpha mask photoshop is already using in the layer setup?
