I was testing a new background idea using lights, and unfortunately I didn't make the lights go wide enough to cover the whole background. Lesson learned! I have tried duplicating the lights, but the shading of the paper background is making that extremely difficult. Straight up cloning didn't work. What I did here was make a layer of just lights, merged it with a solid color layer, and then masked it off the subject. It doesn't look as...real, somehow, I think maybe because I'm losing the little bits that were the wires connecting the lights? In any case, I wanted to see if there was a better way before I tweak the lights and clean up the masking.
