Weird Lines in last developed roll?

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!

You should be able to see the lines on the negative strip. If needed, use a magnifying glass. It helps sometimes if you change the angle under which you look at the strip.

If you develop your films in the traditional tank where the film is wound onto a spiral, I see three possible causes for the scratches (if it's that what they are)

1. Dust or uneven edges in the camera
2. Ditto on the lips of the film cartridge (did you re-use the cartridge?)
3. Wiping the film with a pair of tongs (to remove the remaining water drops)

I took a loupe to the negatives today, and the fine lines indeed run thru all 36 exposures at the exact same locations. My guess is something fine was caught in the canister (not re-loaded, I'm a one and done shooter) and just got onto the emulsion. I typically run thru the strip once with a paper towel after hanging, but that couldn't have been the cause here as that is done by hand and the line is too fine and too consistently in the exact same location. 

 

Ah well, win some lose some lol.

You can run your fingernail along the film to see if the scratch is along the emulsion or base. There aren't many places where the image portion of your film touches the camera, so double-check the pressure plate if the scratch is on the base, or on either side of the shutter if it's on the emulsion side.

Black lines indicate scratches on the emulsion side, so something in the cassette light trap or the path the film takes through the camera. But run to your waste bin and retrieve the end of film attached to the spool that hasn't been through the camera and see if that has scratches which would suggest a faulty film.
