I think there are basically two types of portrait photographers: The first likes to shoot with “available light” by which they really mean “every light that’s available.” The second group, I’m mostly on this team, prefer to use as few light sources as possible…

My friend Mark Toal often writes about his experiences making photographs with his iPhone. You can follow him on Instagram @marktoal and see for yourself. My friend Ralph Nelson, produced an impressive coffee table book called Botanica, using nothing but a couple of iPhones.
