How to Use Infrared Film


I have heard that IR film must be loaded in total darkness-however, I have a disability which prevents me from handling something that requires a certain amount of dexterity. Is there any way to load the film like other film and just give up one or two exposures (like accidentally exposed film, for example)?

  I think that may be a precautionary thing rather than mandatory. Is it that you have to see what you're doing? Or is it that you usually end up having some of the film pulled out of the canister because of your disability? You wouldn't need to be in a totally dark room; you could cover up the camera with a dark cloth, or T-shirt, with it in your lap. It's recommended that you load regular film in subdued light, but you don't have problems loading a roll outside in broad daylight.

Steve McCroskey   Gregory, thanks for the info. I load film without any problem. I just didn't know how the IR film loaded!! I always use the first roll of any film for experimenting -just finished a 36 exp. roll of 200 slide film, of which I guess 50% will not turn out. But I will see!! Thanks again.

  The thing about loading IR film is that the felt at the cartridge opening does not effectively stop IR rays the way it does visible light rays. Also, at least for Kodak's IR film, there is no anti-halation layer to block stray light from the backside of the film from reflecting back onto the emulsion. With respect to loading the film, that also means that the film leader sticking out of the cartridge has a tendency to draw light/IR rays into the cartridge, a la fiber optic.
