Description: A little more subtle, not so colorized, a bit sharper. The fingers around the Lagoon came out a little better, as did the shapes behind the dark clouds in the Trifid. Stars are also a little bit better controlled. Used about 5 different masks, well more if you count the combinations of various masks, throughout the process
