If you want to make something more interesting, it's important to know what not to light. I know that a great photographer said something like that, but I cannot remember who that was or what his or her exact words were. It's a phrase that I think about constantly though. One of my new favorite shadow creator combinations is a beauty dish with a grid. Soft, fairly large, but most of all, very constrained. I would say it is easily disciplined.
Here are a couple of my favorites from a shoot that my friend and client Ed and I did earlier this week. Ed is a retired accounting professor and an up-and-coming actor and singer. We created hundreds of actor headshots, but once those were in the can, we worked on some additional dramatic, less traditional shots.
