Lines where there shouldn't be any

[bwrules]

I get these lines close to the middle of the negative. I've ruled out light leaks as this happens with any camera, whether the reel gets loaded in a changing bag or in complete darkness without it. I am thinking i am doing something wrong during the development stage. Or it could still happen when loading reels?

Any ideas? Thanks.

What size (35mm, 120, ?) film is this?

If 35mm, do you bulk load?

 

[tomalophicon]

It looks to my undeducated self to be creases in the film.

 

[snapshot2000]

I agree. Is it 120? Looks like it was slightly creased loading it onto a (plastic?) reel.

 

[bwrules]

Happens with 35mm and 120. I don't see any creases in the base. The reels are plastic. No bulk loading.

What's odd is that they appear to be repeating, having the same shape. As they only go part way through the image before repeating, I was wondering if you're using a double-stroke camera that advances the frame first halfway then the second part, like an early Leica M3, or other cameras like a Nikon F where you can deliverately double-stroke.

The people in the shot don't look cold, so it's likely not static electricity.

What camera are you using?

 

[bwrules]

I don't think it's the camera since I get them with different cameras, none double stroke. Could it be that I am loading too fast onto the reel?

Most plastic reels I've seen (but not all) use the system where one rotates against the other, while little ball bearings hold the film after it advances. I've never liked these because I always find the film jams. I'm wondering if the marks aren't torsion stretch marks in the emulsion caused by the twisting motion of loading the film.

I'd try a metal reel and see if it presents again.

 

[MattKing]

Is it on the entire roll, or just at one end?

I vote for a tiny crack or other light leak in your developing tank. It repeats because the reels move or rotate slightly during agitation.

I think this might be it. Plastic reels do jam sometimes, and I open the reel, take the film off and reload.

Sometimes entire roll, sometimes just some of the roll.

If this is the case there should be more lines at the outer end of the film. Easy to check.

Can you scan the negative and post that? The whole negative strip.

I had one of those a few weeks ago with a 120 roll of Tri-X not even half a frame and you had to look for it. After having one hell of time loading Tri-x onto a Patterson reel today I'm glad I'm down to my last unexposed roll as I have a huge stockpile of HP5 and will be using that as my 400 ISO medium format film going forward. I had another 120 format Tri-x failure, I had this great long exposure night shot and right smack in the centre a small glob of unprocessed emulsion.
