I seem to photograph a lot of doctors, but I hope to never see Dr. Vaca other then in my studio!  Dr. Vaca is a spine surgeon, and required a portrait for a board of directors.    At first he wanted more of a natural portrait, so the window with natural light was his first option.  Dr. Vac agreed to  try a more professional look, and he liked both options.  Selecting backgrounds can make or break any portrait, but the focus needs to be on the person.
