    Overexposed Negative Edges

    I have been getting what seem to be overexposed edges on my negatives. I thought that it might be a problem with the way I loaded the film onto the reels, but it does not seem to happen with film from other cameras. Any suggestions are appreciated.

    What do the edges of the film look like. Are you seeing any density there or are they clear?

    The edges are clear - the film type and mfg are clearly legible on the edges.

    hi peter
    This looks exactly like a problem I was having with 120 film non pyro development on the jobo.How are you processing the film and is it 120 format.
    Definately looks like development problem. I will go further when I know what film , how you processed and what developer.

    THis particular film was Knoica IR 750 processed with D-76 (1:1). Used 8 1/2 minute development with 5 secs agitation every 30 sec. I got nearly the same result with TMax 400 processed in D-76 - not sure of development times, but it was from Kodak's D-76 time sheet. Both films are 120 processed in plastic tank with plastic reels.

    Looks like a light leak to me.

    Would that be a light leak in the processing container, or camera back?

    Your plastic tank may not be completely opaque to infrared radiation. You really need to process IR film in a metal tank.

    I got negs exactly like that when I first got my OM10. One light-seal kit later and all was fine.
