Help identify black lines/marks running down the edges of 120 negatives

[O HanraHanrahan]

Hello everyone,

I have recently developed 4 rolls of Ilford HP5 120 film and most of the rolls have these black lines/marks running down the edges of the negatives.

I would greatly appreciate if anyone can identify what the issue is? Please see attached photos of the negatives.

Some information on my development process:
Developer Ilford ID-11 1:1 @20°
Processed first 2 rolls of 120 film in a Paterson Multi-Reel 3 Tanks with Paterson Reels
Processed the other two rolls in a separate Paterson Multi-Reel 3 Tanks with Paterson Reels
Used 1 litre of Developer per tank

Kind regards,

Tadhg.

The edges of the film got exposed to light. Maybe the roll wasn't very tight or maybe you had the taped exposed roll in bright light that fogged the edges. Seems unlikely it happened in the camera, but that's possible. That fogging would not be as specific if light was leaking into your development tank.

Hi Don,

Thanks for the reply.
I think that is exactly what happened. I just remembered the taped exposed rolls were exposed to very bright light (direct flash) at one stage

Some people wrap their exposed rolls in tin foil when they take them out of the camera. If you're going to wait a while to develop the film, that might be worthwhile. And at least there doesn't seem to be anything wrong with your development. However, that last photo you showed looks like it might be a sticky shutter.

A bit redundant now as Don has already said exactly what I was going to. I happened to me with an old Agfa Isolette folder. It just hadn't rolled the film and backing paper tight enough when winding on or I hadn't pulled the backing paper tight enough when I removed it from the spool before putting it to one side awaiting development

I have treated myself to a dozen or so single roll canisters -- Freestyle has them, also B&H, albeit a slightly different lid arrangement I suspect a few other places also carry them.
I also before the last "major expedition" acquired a few 5-roll carriers. Maybe it's my age, but I prefer the old school black ones. Though I admit I've no idea how opaque the fancy colors are. I can agree colors might be useful to identify different film types.

It can be pretty easy to mix up what type of film it is from just the way a 120 roll looks when it's at the end.

1. Light piping. The exposed roll was not wound tightly enough and left in too much light. I use black plastic cases of all my exposed 120 film.
   
2. Some to the black is from the plastic or steel development reels. There is not a lot one can do about that other than to scrub the reels with a tooth brush in hot water after developing film.
