I look at photos all the time. On the web, in books (if I'm lucky), in person (if I'm really lucky), any way I can. I believe that having a varied visual diet is good for me as a photographer. Also as a person, but that's a bit less quantifiable.
One of the ways I make sure I'm seeing photos that are fresh and current and appeal to the public as a whole is by subscribing to magazines. I subscribe to quite a few of them. And when I see an image I love, or where there's something I think I can use - a pose, a lighting angle, a feeling, a concept, whatever, I tear out the page. My favorites I stick up on the wall in my office as inspiration, in the hope that after seeing them over and over I can absorb a bit of their awesomeness.
So what about you? How do you stay inspired? Do you believe in looking at other people's work?
