    I agree with the dimpled pressure plate theory. Year's back, I ran a roll of HIE through a Canonet G-III which uses two large "rivets" to attach the pressure plate to the camera back. When I processed the film the two rivets were softly, but annoyingly, in the background. I've learned to look at the pressure plate before putting a roll of HIE in a 35mm camera.

    Thanks Jaap Jan
    I see tons of that stuff on my really expired 4x5 HIE. Always blamed it on the age of the film but maybe it's something else?

    I use ID-11, acid stop, and ilford rapid fixer. Rotary processing.

    Isn't HIE sensitive to gamma radiation?

    Gamma radiation can cause fogging if stored over a long period of time
    I've heard but it's not as prevalent as light, in radiation terms.
    I don't know how Alpha and Beta radiation would affect it, if it would.

    If you really want to solve this problem just put Edwal LFN into your developer. I had the same problem pre internet days and was always exacerbated by the air bells. LFN fixed this for me and I have never developed any roll of film since without using it, and have never since had an air bell. HIE is horrible for air bells, I don't know why. Pre wetting is also a good idea, but I only do that with Pyrocat and Pyro to get an even stain. LFN solved my problems with HIE. I doubt you would get a bad batch of film with Kodak. They are just too good at quality control. Foma and others.......
