Horst P. Horst (Horst Paul Albert Bohrmann)
[Photographer, b. 1906, Weisenfels/Saale, Germany, d. 1999, Long Island, New York.]
I don’t think photography has anything remotely to do with the brain. It has to do with eye appeal. 
Lighting is more complex than one thinks. There appears to be only one source of light. But there were actually reflectors and other spotlights. I really don’t know how I did it. I would not be able to repeat it.
