Using Channel Luminosity to Make Selections
by the way, something that I've been doing throughout the entire class. I don't know if you notice I've been doing the revert feature and photo shop. I don't know if you guys know about that. When you make an adjustment to a file, sometimes you make a big mess that it's just easier to go back to what the file was like when you first opened it. So you're going to file Revert.
