I wanted to pin this photo to see a professional set up for using lighting gels. Here there is technology used including a stand with the lighting gel over the light which is being bounced onto a stand with lines in to created shadow on the model.
senior pix -A masculine, relaxed look. The dark tones (gray and denim) look great with the dark hair. With that said, if you're blond, a bright white shirt with denim might be your thing (not that you can't pull off the gray -- we know you can).
I especially like the first photos lighting, and the set up of the first black and white portrait facing the camera, and the last photo on the right, though the last photo is farther away than I might prefer
