Digital photography

Are martin parr and graham parr different people? Seen a few exhibitions of Grahams, and liked some of it (the dead pan, medium format documentary stuff), and felt physically repulsed by the rest (the highly saturated oddly framed grotesque shots of people at the grand national, though I think maybe that was the point?). Or maybe I'm being rubbish with names and it was Martin?

Sounds like Martin.
