Diane Arbus was an American photographer noted for photographing marginalised people. She was initially a commercial photographer but quit that in 1956 and wandered New York City looking for people to photograph.
Her photographs of unusual people along with her photo of a boy with a grenade are iconic, if not shocking. In fact most of her work makes the viewer sit up and question what they’re seeing and wonder what the story is relating to the subject.
I will re-visit Arbus’ work at a later date.
