A quick note on dust and scanning film.

Only computer monitors appear to be more of an attractant to dust than film.  If there is any static charge on the film dust will stick to it like glue.  So I recommend Acme brand (If Acme exists I don’t think they actually make Anti-static brushes but you can Google it if you want).  In any case I use an anti-static brush which dramatically improves the effectiveness of any air blower.   I also have another one that I use for removing dust from the front element of lenses,  this is often enough as the less contact you have with a lens element the better in my opinion.  Another thing that I use to reduce the dust in the area where my scanner is, is an electrostatic air cleaner which uses the static charges it develops to pick dust out of the air as it passes through.  It’s not easy keeping dust out of your scans but it’s effort that you don’t have to spend later in post processing.
