Diane Arbus - Application, Context and Technique

Photography has changed a lot over the past 90 years.
One example showing this is how Rich and Powerful people had portraits made for them (how they want themselves to look) to the works of Portraiture photographers depicting their inner-conflicts and catching their clients in moments when they are least prepared.
One Portraiture Photographer who is an amazing example of this is Diane Arbus.

Diane Arbus was born on March 14th 1923 in New York, to parents David Nemerov and Gertude Nemerov who owned Russek's (a famous Fifth Avenue Department store.) Due to her family's wealth, Diane was safe from the effects of the Great Depression while growing up in the 1930's. She started a commercial photography business with her husband (Allan Arbus) creatively called "Diane & Allan Arbus" with her as the Art Director and Allan as the photographer.
In 1956, Diane quit the commercial photography business and began photographing for Esquire and The Sunday Times Magazine.
This experience led to her changing her approach to photography, starting to establish a strong personal relationship with her subjects and re-photographing some of them over many years to capture not only physical changes, but emotional changes.

One of her most well-known photographs is of a Child with a Toy Hand-Grenade in Central Park titled with the same name. She is well-known because she used her camera to strip away anything that she didn't want her audience to see, however, this led to major criticism and that she photographed 'freaks'. Which is not how she wanted to be remembered. In 1971, Diane took her own life and led to people wondering if she saw herself in these "freaks" that she was photographing. Was she led by curiosity, or did she want to show her feelings through other people?
