For some reason, the iSight camera on my Macbook seems a lot worse than others I have seen. It's really fuzzy and grainy in both iChat and Photo Booth. Are there some settings that I can change, or should I take it in to have Apple look at it?
I'm sorry to say, but you might look whether there's a plastic cover to take off (like they have on new mobile phone screens and similar) _or_ if you just have to, well: Clean it. A smudgy iSight doesn't make good pictures.
