The problem with fogging in Kodak HIE is that the film acts as a light guide like a fibre-optic device. If you take a conventional film out of the plastic canister in daylight, the film will hardly be fogged more than a few millimetres beyond the opening of the cartidge. With HIE, you may easily fog about a foot of film. Also, HIE is very grainy, which means you shouldn't sacrifce too much of your negative by cropping.(posted 8637 days ago)Regards, Thomas Wollstein
