dust on film: I must be the only guy in the world (allmost) that uses a "centrifuge" as the last step in my developments. I can't live without it - and there is NO dust or chalk residue after that...
you can buy one small one cheap. (I've just seen a few for about 40$, used)
I don't know whether the name Centrifuge is common in USA but I made an attachment for you to look at - you know: the gizmo we use to remove most of the excess water after washing our clothes..
