One of the things I'm not very good at yet in my photography is cropping. I tend to just frame what I want in camera and trust that it can't be improved much after that. But I've seen some really striking examples of what skilled cropping can do to a picture and I'd like to get better at it.
What I've learned so far is that often my horizontal shots, and in particular my landscapes, start to look a lot better when I crop them to a more cinematic aspect ratio. I guess I really shouldn't be surprised that my eye tends toward that.
Edit: The old version of this picture was flat in a way I didn't know how to fix in iPhoto so I got a copy of Aperture and punched it up. And so the hobby goes.
