In some light poses I've seen where they add a whole mess of black lights. Why are they black? Do they subtract light? And how do you make them another color if you want? And are there any tips on adding more light where you want it? The light set I added was pretty good, but I thought the face was too much in shadow. I tried changing one of the black lights because there seemed to be so many. When I couldn't figure that out, I added a new light. I moved it around checking left front and top views. I aimed it from the ground up at the face but it didn't seem to add as much light as I wanted. At first I didn't think it was working at all, but when I rendered I saw that part of the face was receiving some light. I probably need to make the radius or whatever it's called wider? Thanks.
