    Foma Pan 100 120 Negs are Blue, 135 Negs Are Clear?

    Hi Everyone,
    I just hung up my first roll of 120 Foma Pan 100 to dry. To my surprise the negs have a bright blue tint to them. I've seen slight pink tints on some of my other films (Pan F+ I believe) but not like this. Did I mess up the processing? I pre-soaked for a minute (the water poured out blue-green) Rodinal 1+100 for 7 minutes, two one minute rinses in plain water for stop, then 6 minutes in fresh TF-4 fix. Then a hour long soak for five minutes, dump, and refill for the wash. Negs look nice otherwise. What's really odd is that about a month ago, I shot a 135 roll of Arista Edu 100 which is supposed to be the same film, but it did not have the blue tint. I processes this roll the same as the 120 roll. Any idea or suggestions?
    Thanks,
    Marc

    normal, this is the film base.
    D-76 is a standard developer, although not one I use.

    Strong colour cast on film base may indicate underfixing.
    I like my film stirred, not shaken.

    I used to shoot a lot of Foma and the base is always blue. I have no idea why but it's normal as far as I can tell.
    f/22 and be there.

    Correct, the 120 is blue, and 135 is clear. I have both, and was disappointed the 35mm wasn't blue.

    They need to put a warning on the box or something; I think everyone who's ever shot Fomapan in 120 has had this same "WTF?" moment.

    It's clear in sheet sizes too. I don't know what's different about 120 that leads them to use this rather odd base.

    The lady of the house has to be a pretty swell sort of person to put up with the annoyance of a photographer.

    Totally agree.

    The first time I developed Foma in 120 I thought I did something really wrong and jumped on the internet looking for help.

    I wonder how many people go through this, assume there is a defect in the film, and never use Foma again as a result.

    Now days I love the blue color. I think it's rather nice looking

    Good to know. I have 10 rolls of the stuff and would have been a bit concerned with the first roll.

    There is no guarantee that just because the name of the films are identical that the film is actually the same across the different formats. It is not suprising that the bases are different considering the different mechanical considerations required for the different formats.

    Not only the film base may be different but the emulsions may also be different. Note the emphasis on the word may. As an example Kodak Tri-X and Tri-X Professional. This was discussed on an old thread.
