I am not sure if it's from the camera or the development process. I use a jobo rolling tank to process and processed two rolls of b&w film using the cinestill 2in1 df96. Only one of the two rolls had the problem throughout the entire negative strip. Not sure if its a double exposure or from the chemicals?
For additional context this is a roll of lomo kino and both rolls I shot where on separate cameras.
I thought it might be double exposed too, but the lack of frame lines might point toward processing issues. Could the film have been rolled onto itself, giving two images? But in that case, you would think there would still be some frame lines.
It is a double exposure, and the OP gives a vague clue why there are no frames lines, it's a Lomo Kino camera, for making 35mm movies. The OP should either bend back the leader after the film has been exposed to stop it being accidentally reused, or better still wind it all the way back into the cassette. Being a Lomo camera it would also explain the light leaks along the film edge.
I believe the OP was referring to Kino film. Lomo brands all their repackaged movie film as Kino. That obviously wasn't shot in a LomoKino camera.
It is hard to tell from what you posted what the actual problem is. Just by looking at the somewhat repeating pattern it might have been a bad cassette. Both edges of the film are fogged which is a bit unusual. Perhaps if you showed us a picture of the whole roll on a light table you could get a better answer. I doubt it is a processing issue. The only way to get a light leak with a JOBO is to not use the center spindle.
does lomo sell a film that is previously exposed ? I remember reading somewhere that at some point they were going to sell or they wanted to sell or there was a demand for film that was pre-exposed with a single exposure for users to then put in their cameras and expose again. not sure if I imagined that or if it happened .. no clue what happened with your film but if you like the results i'd buy more of this film and and put it in the same camera and process it the same way and see if it comes out the same. sometimes double exposures and problems processing / exposing can lead to magical images.
