    What are these marks on my film?

    This seems to have started when I began using the JOBO processor and 2509n reel, I can't figure out what it is... It's only on the side WITHOUT emulsion. Everything else in my process hasn't changed since switching from the MOD54 to the JOBO 2509n...

    It's been showing up with both Rodinal and DD-X that I've used... Again everything else I've done is the same...

    do you use/have the plastic inserts for the 2509n reel?
    without them there could be banding from the flow of the chemistry, I've never seen it,
    but often heard of it. Most people prefer the 3000 series drums for sheetfilm cause of this.

    Yes I use those inserts...

    I'm thinking it could be too much photoflo/wetting agent but I've never had this issue before and I haven't changed my amount I use...

    This tiny lines ? On dry film ? It doesn't look like a too much wetting agent. Can you scratch it off with finger ?

    I am just curious if it is a deposit or what else. Never seen such a thing before. Very strange.

    I've had the same thing show up on my film. I think they are streaks caused by excessive wetting agent.

    They don't show up in the print.

    Yes, doesn't seem to affect the scan, and is NOT on the emulsion side.

    I'll use less wetting agent and see if that helps.

    if you use photoflo, you only need a few drops/ tray, tank &c
    more than a few drops &c is bad news ...

    a small bottle seems to be a lifetime supply

    I developed a roll of 120 film last week and skipped the wetting agent all together. The streaks are gone!

    I'll need to get a dropper to control the amount of agent I use. I've just been guesstimating it.
