Ok in photoshop when you start off with a trans canvas, then you add the black to it and make a new layer..after that you have to brush on that new layer but for me it doesnt brush for some reason i keep click my mouse a million times on this new layer and nothing happens someone please help
Press Ctrl+D and then try to brush if not make sure your layer is unlocked. If that doesn't help let me know.
by any chance do you still have black as the color you are working with? because you cfan't really brush black on black change it to white or any other color if it is
