Where do you hang your films to dry?
Lately I've been hanging my film outside of the house, in a breezy spot in the shade (under the car-port). I'm getting a lot less dust on the film this way, compared to drying the film inside the house. I develop my film late in the evening, and leave it to dry overnight. I'm getting fewer scratches on the film too by not handling it before it has dried properly.
Your kidding, right Chris? In my part of the world, dust and pollen is ever-present in the air, along with low humidity. The problem I have with active air filtration is that I can't control the ingress of 'new' dust into my darkroom area, since I don't have a double-door airlock. I feel the air disturbance caused by the filter unit's fan may stir up just as much dust in the air as it supposedly removes. It may be filtered, but it's not laminar airflow like in a cleanroom.
So I've taken to using my second bathroom, which is all ceramic tile and cultured marble. I remove all towels and throw rugs ahead of time (i.e. no lint-trapping fabrics), run the shower on hot to humidify the room.
I transport my finished sheet film from the darkroom to the bathroom using a tupperware tub of distilled water and photoflo, covered. I also throw in some 90% IPA right before hanging the negatives.
Then I use metal bulldog clips, hung from a metal curtain rod using metal wire christmas ornament loops. My idea is that the use of metal will help eliminate static problems caused by using plastic materials. Then close the door and don't go in for at least 4 hours.
