Weird lines in last developed roll?

[shawn2nd]

Hey Guys,

I’ve yet another question for the forum in my never-ending journey of developing my own film haha. My last roll I developed, I have these lines showing up on every exposure. They’re only really viewable when you zoom in, but still quite weird (screenshot attached).

Have you guys seen anything like this previously? I’m wondering if I messed something up in the developing process to get such a result, or if maybe something in my camera is finely scratching the film, or if I should maybe really give up on Fomapan

Camera - Ricoh FF3
Film - Fomapan 100
Dev - Kodak HC-110

Many thanks in advance!

Something is scratching the film, yes. Specifically the emulsion-side.

Common causes are:

• Abrasive elements around the film gate in the camera.
• Improper use of a bulk roller for 35mm film (forgetting to open the film gate on Watson-style loaders)
• Sharp inclusions in the 35mm film can felt trap; e.g. sand (esp. if the film roll has been stored outside of its plastic container).
• Use of some kind of squeegee on the (wet) film after processing.

or if I should maybe really give up on Fomapan

Fomapan as such does not come with this kind of damage from the factory. It's virtually always caused during handling or processing.

Do you squeegee the film?

We can limit to points 1 & 3, I took a loupe to the negatives and the line is in the exact same spot across all 36 exposures :-(

I run thru them once with a paper towel, but if that would've been it the line would be a bit more erratic. I have taken a loupe to the negatives, and the lines show up at the exact same spot consistently across all 36 exposures :-(

Only the shiny/non-emulsion side, I hope?

Yeah, that suggests a camera problem or something sharp in the felt light trap of the cassette.

I've gotten scratches from a camera, but to be honest - the lines there weren't that straight, I have no idea why. Perhaps the inertia of manually advancing the film has some role to play. On the other hand, I have exactly such ones from a bulk loader. So I stopped using them.

Hang it in a dust-free room and pour photo-flo water liberally onto the film.
Just leave it there to dry.

If you haven't irretrievably thrown it away get the end of film attached to the spool out of the bin that hasn't been through the camera and see if it has scratches, this may indicate a faulty film.

The source is dirt in the film path including on rollers and pressure plates.
