At first glance this site might seem photography-hostile -- after all, it's called Unphotographable. And each entry begins, "This is a picture I did not take of ..."
But it's produced by a guy who describes himself as a photographer and writer. What he's doing, he says, is recording what he sees when he doesn't have his camera, wishes he'd taken a shot, or "had been brave enough to click the shutter."
And what he comes up with is an exercise in attention to detail and descriptive writing -- something well worth focusing on as you're out in the field. His entries are short, vivid passages on what he's looking at. Like a picture in words. It's pretty cool.
