I saw this picture of Jerry Yang, founder of Yahoo, and I like the lighting. The strong shadow coupled with his pensive mood really complements the article about him resigning from Yahoo.
How do you think this was achieved? What's certain is at least there are two lights here. The main one from front (creating that strong shadow) and a smaller one lighting his face. But I suspect, there are more lights involved. His whole body is well illuminated. You can still see the suit's wrinkles even on the left side. Was a reflector used?
Can we improve the setup even more? Can we somehow make the shadow totally uniform? Especially around the head.
