Two of the photographers that inspired me were Yousuf Karsh and Leni Riefenstahl
Riefenstahl who lived with tribes people in Sudan and Kenya for many years while photographing them and learned to scuba dive at the age of 70 so she could photograph the undersea world. I have a few of her books and take pleasure in flipping through them from time to time.
She was not so popular and shunned by the western media due to her films for the Nazi's during WW2, she fell in love with Africa and spent many years there.
Karsh, was a master of B&W and his pictures have a life of their own, just brilliant work.
I have his books as well.
