Using compressed air can hurt, though. There's stuff in the mirror 
box/shutter assembly that doesn't like high winds, and if you use 
compressed air that is bought in a can, it contains propellants that 
can make a real mess of a sensor. Even air that is compressed by a 
compressor in a shop, etc. usually contains oils that are nasty 
things to clean off. The only air that is generally OK and readily 
availble is that from a scuba shop, but it still is too violent for 
inside of cameras.

Brushes and swabs and bulbs are the way to go.

Cameras with CCD types of sensors attract more dust than CMOS types 
theoretically. I don't bother turning the camera off when changing 
lenses. Tried it for a while, but could see no difference.
