Mortensen was mentioned in a critique of one of my photos yesterday (Kayt's Back). He's not someone I'm very familiar with so I've done a bit of scrabbling round on the web. He seems to have been quite influential at one time, but then fell from grace as he went out of fashion. I'm very interested in him, but I'm also very interested in how he's perceived by contemporary photographers. So I have two questions: If Mortensen was alive today, what could he teach us? And if you could go back in time and teach him something, what would it be?
