I live in suburbia, and there's not a lot to take pictures of around here. So I contacted some friends who skateboard, and I would like to do some photography and/or videography for them Some questions I have: 1. What's that lens they use to create the bowl type effect on pictures and videos? It's that one where the subject seems to get closer towards you as it moves by you. 2. As far as pictures go, what's the best way to get continuous photos within half-seconds of each other? I'm using a Nikon D40 by the way. I might have some other questions, so I'll post them on this thread. Thanks to any who can help me out.
