Using LR 6, I'm trying to remove wrinkles in a portrait. I have found the spot clone tool and am trying to figure out how to do it. It looks like the spot/clone tool is used to clone an area, i.e., remove a bird from a picture. What I've used in other programs is a tool whereby I can designate a spot of color, and use the tool to brush the color over whatever I'm trying to erase, like wrinkles. What am I missing? How can this be done in LR?
