another thing that you have to be careful with when using compressed air (like
those now commonly found for cleaning computers) is to make sure that your
curtain will not be on the the direct receiving end of that stream of air.
especially if your curtain is cloth like that on the olympus cameras. i
remember reading this somewhere that the blast from these thing are enough to
damage the curtain. what kind of damage, i don't remember and i don't want to
find out by expereince. but using those small blower brushes should be safe.
