I suppose this is technically things I love about photography (I, being Jess). But I'm sure Rene would agree, so we'll pretend it's things we love. I could list a lot of clichés about capturing moments and love and sweet things like that. But I won't. Not to say that I don't mean them, I do. But you've probably heard them before so I'll save the fancy spiel for my website.
The thing I love most about photography is not the fact that you can capture a moment, but that you can create one.
Photographs have a dream-like quality to me. They always have. The light play. The short depth of field. The grain of film. The blur of a long open shutter... We can't see those things with our own eyes. They don't exist in our world at all until they're brought into existence through a lens. And with a camera, we can create and control them. We can imagine and commemorate a dream world all our own.
