    Vertical Lines on Prints / Scans - Please Help!

    Hi, I've been shooting 4x5 for the last 4 years using a Chamonix 0451H and multiple lenses. I have noticed that on my last 2 batches of film I am getting vertical lines on my prints / scans (I can see them on the neg through a loupe). The two examples shots have been taken with 2 different lenses (150mm/65mm) and 2 different holders.

    The two images both have vertical lines despite one being shot in landscape orientation and the other in portrait.

    I shoot Hp5 and process with DDX in a mod54 / Patterson tank. Does anyone have any idea what could be causing this?

    Please excuse the crappy drawing on the images to highlight the issue.

    Hello jmo,
    It looks developing lines, But the films orientation run against that!!!
    I assume all films has the same orientation in the Mod54, all vertical? I do not use that drum actually.
    Is it lens flare? Specially for the first example.
    Did you notice any unusual distributions of grain? Specially in the second example.
    Hopefully, prints deserve a lower grade or half grade, see if printing on lower contrast may conceal the lines?
    Did you check the minimum amount of solution? Developer? Temperature? Agitation method?

    The generosity of spirit in this forum is great, its warmly appreciated.

    Plus of course, how did you develop the prints?
    All points mentioned are equally important as initial step.
    Then narrow your search every step you exclude one or more factors.

    Do you use a squeegee on the negatives before drying them?

    Did you ask your self in the first place, why he used squeegee on "Horizontal mode" sometimes and on "Vertical mode" other times, arbitrary?
    All lines are vertical regardless film orientation.
    Squeegee is the trend this time, but I do not think it's the cause, unless confirmed by the OP.

    The more likely alternative is agitation/ flow mark related & we don't know what sort of agitation pattern was used. Entirely possible that the vertical ones come from the core of the mod54 & the horizontal from the fingers used to hold the film in place. I've seen all sorts of strange marks from various plastic tank contraptions on sheet films over the years and almost all of them related to the poor flow patterns generated inside the tank. Jobo Expert drums, tray development or stainless hangers & deep tanks are really the only way of giving yourself a fighting chance against them.

    my money is that it's that tank you are using to process. I suggest shooting two negatives of the exact same scene, process one in your tank and send the other to a reputable lab, or better yet process it yourself in a tray. your lines look like bad agitation due to the design of your tank to me.
