    streak across MF negs....

    See attached photo. Every once and a while I see this streak across my medium negs, like the one you can see in the sky there to the left of the palm tree. it's not a light leak as i see it from different cameras (this happens to be my Hasselblad 500CM, but I get it with my Rolleiflex TLRs sometimes, or my SL66 or even my Fuji GA655i), not always in the same place, nor the same film or developer, and for this roll of film only this frame. I imagine it's likely something to do with handling or development process. Ideas? My developer pouring technique? Kinking the film in the changing bag? Thoughts?

    What do the negatives look like ? Does the density extend across the entire film? Is silver density or something on the base side?

    This is Kodak Tmax 400 (TMY-2), by the way, developed in HC-110. Stainless steel canister using Hewes reels.

    Only within the frame of the image, looking through a strong light at the neg it's a faint darker streak, no indication of any physical damage to the film on either side. I'm thinking perhaps flare? Lens was a 40/4 CF T* FLE Distagon.

    Could it be a bending part of the negative inside the canister? Had this stuff several times when I was a bit grumpy on the installation process, experiencing difficulties inserting it..

    There is no canister for 120, so it is not that. It could be from bending. More likely it is a processing artifact. Sometimes developer drips over a piece of negative and starts working before the entire negative is immersed. Sometimes the film kinks on the reel and creates a hot spot where the effective agitation is greater. Sometimes other things happen. It is important to load the reel carefully so that the film is evenly wound in the slots. it is also important to pour in the developer quickly, in one continuous pour.

    Thanks for the replies all, here and in PMs. I've narrowed it down to likely bending by me when loading onto the reel in the changing bag. Will try with a framed bag, or in a darkened closet without the confines a smaller changing bag has that might be conducive to be doing this. Appreciate all the suggestions.

    I would try to bend and fold a bit of negative before giving it a bath. From what I recall, this happened indeed when the sliding process on the wheel was resistant making the film bend obviously, whatever canister or not you call the final recipient. Cutting two tiny "ears" at the head of the film before inserting it could help. Have fun!
