Is there any controversy over heat drying? Commercial labs do it all the time, and have done for many years. If the film is stretched or weighted to prevent curling, and the drying cabinet is dust filtered and limited to about 45 celsius, then it's difficult to see what possible harm the film can come to. Most modern films are coated on a polyester base anyway, which makes them as tough as old boots.(posted 8255 days ago)The only thing I'd have against using drying cabinets in a student environment is getting students to follow proper procedures. This means not sucking dust into the cabinet by slamming the doors open when it's already in use, and not scratching other people's film by careless hanging.
