Keith Carter was on Texas Country Reporter this morning. He is a Texas photographer and also a teacher. I haven't done much research on him, but here is a quote from the bio part of his website...

Keith Carter is an internationally recognized photographer and educator. Born in Madison, Wisconsin in 1948,he holds the endowed Walles Chair of Art at Lamar University Beaumont, Texas. He is the recipient of the Lange-Taylor Prize from The Center for Documentary Studies at Duke University, and The Texas Medal of Arts. In addition Keith Carter has been the subject of an arts profile on CBS Sunday Morning, and Anthropy Arts produced a documentary DVD of his work. He is the Lamar University Distinguished Faculty Lecturer, as well as being named the 2010 TSUS Regents Professor.

In the segment on TCR, Keith was shown shooting film with a Hassie - I assume a 500cm. The unfortunate, and ironic part is that he mentions he was diagnosed with ocular cancer in his left eye, which has left him partially blind. He said that everything looks dirty through his left eye.

And so he's started a new set of work, based on his left eye vision. He said that everything is interpreted as he sees it. It was really quite interesting, and I much do more research on Keith.
