Streaks and Kodak appearance on developed film

[pentaxuser]

Thanks, Dave for the enhancements. I can just about make out the word Kodak. The numbers are much easier to read now

I've looked again and again at those photos and I can't for the life of me see the word "Kodak" in those marquee boxes. Can anyone lend a hand? Are they vertical, horizontal, large letters or small? I feel like the stupid kid that can't get the obvious answer to the puzzle.

Hi -

This has been happening to me for some time. In these attached examples, there are two problems I see. The first and most obvious are the vertical streaks in the shot.

At first I thought it was my lab- maybe they did not clean properly and the lines were chemical. But then when I developed my own black and white shot using Fuji Acros Neopan 100, I saw the same problem. Then I thought maybe it was from freezing my film. But the problem came back when I loaded and developed film that was not frozen. I then thought it was my Yashica D, but I got the same problem using my Yashica 124-G.

Not sure what is causing these streaks now. Maybe the pressure plate in the cameras?

The second problem is that you can see the KODAK printed words from the film (marquee boxed in red).

Does anyone know why these two things are happening?

Thanks in advance.

Oliver good luck with your troubleshooting. Knowing that the problem is on more than one camera and more than one film really helps. Let us know when you've cracked it and what the problem actually was.

I did just want to mention though that you've made a wonderful portrait of that street performer; I know the vertical lines are an error, but in this case it's a happy one and I think those stripes are adding to the image, like the performer is advancing through a scrim. Maybe try printing it?

Thanks @jawarden .. Others have had the same compliment. I agree with the aesthetic of the lines somewhat, but am driven to find the cause of it. @Ian C has a very good take on what this could be:

The lengthwise parallel lines appear to be “cinch marks”. They occur as the emulsion side of the film scuffs over the film (or paper backing in the case of paper-backed film) on either the supply or take-up spool. This happens when there is far too much resistance to advancing the film in the camera easily (as it should). If the film advances with considerable resistance, then this is the likely cause and indicates that the advance mechanism needs service.

While it’s possible to obtain similar-looking scratches from damage to a film roller or the pressure plate, this usually makes only one scratch and forms on the back of the film. This type of scratch is far less likely with paper-backed roll film due to the paper backing.

It is a good idea to be sure that any surface that can contact the emulsion side of the film is clean before loading film. If the cause of the problem is cinch marks due to hard winding, then the marks are likely to persist no matter how clean the film-contact surfaces. If the scratches are on the emulsion side, it is likely cinch marks. Cinch marks are unlikely on the base-side of the film (perhaps even impossible).

A few years ago a Google search brought up considerable information on cinch marks. There seems to be far less information now. One of Andreas Feininger’s photography books shows film in a 120 roll-film camera with identica marks to your B&W shot along witht the explanation. Cinch marks were a big problem in motion-picture photography, expecially in movie-theater projectors thar weren’t serviced regularly.

As we get farther into the digital era the old data gets slowly discarded and the illustrated diagnoses to once-common problems are harder to find.

Suggestion, do not roll the exposed film so tightly before taping. Tight rubber band also leave marks.

Thank you. I feel it's come down to improperly feeding the film as well as me applying pressure to the roll when initially spooling it to make it as taut as possible. I will also refrigerate and not freeze the film. I use film often enough, I might as well not. Much thanks.

You can keep 120 film in a freezer (or fridge) as long as it is in its original sealing foil and the foil is intact. After removing the roll from freezer, just give it enough time to warm up befor you tear it open. The same is true for film that comes from a fridge (just the warm up time is shorter). Do not put exposed film in the fridge or freezer.

@mnemosyne thanks, sounds like good advice. After developing a handful of film, I've come to the conclusion that the problem was because I was making the film taut in the loading process. I was applying pressure to the film as I wound it so it could be tight. Now, I just load it normally and all seems good.

I never experienced such streaking concurrent with the backing paper issue on 120 TriX. Definitely take film out of chilly temps well before you plan to load.
