I have seen his work on a couple of occasions and agree that the prints are beautiful to see in person. Mark has the ability to take very banal subject matter and extract certain nuggets that capture your attention. A couple of folks have mentioned the evidence of people now gone from the scene. One of the aspects of his work is his ability to edit the scene down to a few key elements. His best images strike a wonderful balance between the subject matter and tonality of the print. Niether over powers the other.
