- Open a blank layer above the adjustment layer, and press CTRL+SHIFT+ALT+E to create a stamp visible layer

- Get the magic wand tool out of the toolbox, then click on the black areas. Hit delete on the keyboard to delete these areas. You may have to adjust the tolerance setting on the tool's option bar. I used 32.
