I don't know about you, but I think clouds are amazing, and I think that the best way to show people this is through photos. I'm no professional photographer, but here are a few tips on how to take great photos of them.

It doesn't really have to be that hi-tech, the only things I'd say are important are a good zoom and an option to change the exposure (this will normally be found under manual options).
I use a Canon Digital Ixus 75 for these pictures.
