Line up your shot. Make sure its composed perfectly. Now take another camera and take a picture of the view finder. That's the premise behind Through the Viewfinder (TtV) photography.
The thing about TtV that I love is that the pictures end up looking like nothing else I've seen. A little Holga mixed with a bit of Diana and a pinch of Lomo LCA with a little Lensbaby added for good measure. I get consistently remarkable lo-fi looking photographs from a combination of old school and high tech. Ghosting, grime, flip, trap, bubble - the medium has spawned a whole new set of words and phrases, too. It's so damn quirky, it's cool.
Sounds like something I'll have to try out
