I first came across portrait artist Martin Schoeller when he published his "Faces of America," and I've since seen him pop up in various places.
What I love about his work is that, as he says on his About page, the people he is photographing "are treated with the same levels of scrutiny as the un-famous. The unknown and the too-well-known meet on a level platform that enables comparison, where a viewer’s existing notions of celebrity, value, and honesty are challenged."
And I just love that.
You can see more of his work on identical twins, close ups of famous people who are still on the same level as the rest of us, female bodybuilders, and portraits.
"Schoeller’s close-up portraits emphasize, in equal measure, the facial features, both studied and unstudied, of his subjects— world leaders and indigenous groups, movie stars and the homeless, athletes and artists— leveling them in an inherently democratic fashion" (via).
