Living 6 houses away from a busy freeway and two houses away from a busy 4-lane road, dust is always a problem. However, based on a how-to article by Joe Farace in Shutterbug Magazine awhile ago, I built his film drying device in minutes and have never again seen dust on my processed negatives!! It is a lightweight drain pipe, atop of which is a heavy piece of cardboard taped to it with a hole in the center into which I insert a 1200 watt Italian hairdryer. I insert my stainless steel film reels into the pipe from the bottom and hold them in place with a pencil or dowel which slides into a hole on the right side and out a hole on the left side. I then turn on the hair dryer with the cool setting, set a timer for 15 minutes, and my negatives dry completely and dust-free. I'd never encountered a successful dust-free negative processing method before this. I highly recommend it! A digital photo of the device is attached.
