There are SO many great photographers and people making outstanding images these days. It's really overwhelming.
I'd certainly second the Martin Parr nomination. He's a sure favorite for me.
Most inspiration for me comes from the Depression era photographers -- Dorothea Lange, Walker Evans, etc. Through faces, circumstances, gestures, postures, etc. they were able to communicate the emotions of a world gone awry.
Then Robert Frank came along with The Americans,
and I love his work.
In the same ilk was the recently discovered Vivian Maier. Some of her stuff so far is worth looking at.
Currently, I'm taken with Jessica Todd Harper:http://www.jessicatoddharper.com/
She published some of her work in the book Interior Exposure.
And her images do just that -- expose (or at least suggest) the interior, the mind and spirit behind the human facade. She adds the depth of personal intimacy to what I try to capture in individuals. But then she has an unfair advantage as she gets to use her family and their relationships.
Anyway, that's what's happening at this time. All is subject to change at any moment!
And thanks for asking.
