    Vertical Streaks In 4x5 Negatives?

    I tray developed two 4x5 negatives of the same shot and ended up with wide vertical bands as you may be able to see in this example. At first I thought it was the scanner, but looking closer, I realized it's in the negatives. Each has the same bands in the same areas. Leads me to believe it's exposure somehow. I don't see how otherwise two negatives could end up with the same bands after tray processing. Each negative was developed separately.

    Light leak, or oxidation during the development process causing uneven development, the neg was not submerged.

    If they're not *exactly* aligned between the neatives this could be related to the structer of the "ridges" on the bottom of your tray. Do you develop emulsion side down? How do you agitate the film? Can you post the scans of both negatives?

    Looks like a light leak, probably from the film holder not being seated fully. Could also be a gap where the bellows isn't tight to the frame.

    I've tried everything I can to create a light leak with my camera and I can't get one to show up. I don't know what causes "oxidation during the development", so I don't know how to reply to that. And, I do believe the negatives were submerged.

    I develop emusion side up and the ridges in my trays are going opposite of the streaks. I rock the trays for agitation. The streaks are in the same spot on each negative.

    I will say this, the streak isn't nearly as visable in the other negative. Much more faint.

    Was the negative with the more visible streaks allowed to sit in-camera (with the slide withdrawn) for a longer period of time than the negative with the less visible streaks? Might be an indirect clue.
