Hi,

Any idea what has caused these streaks,  its on every picture one picture it curves upwards, the next down...and so on?

low quality scans enclosed... got these done at a lab.

oh my god! These have been exposed to seriously high level macrowaves ;)

Just kidding (as usual).
Were these developed by an automatic machine or did you DIY?

Do these streaks appear at the same place on every frame (as they do on the two examples you show?) If so, then I would suspect a camera light leak and not during processing, which would not likely by synchronized with your frames.

I would suspect the auto machine.
If it had been a camera leak, the pattern would have been in the exact same place on every frame, not making a nice sine wave.
Also, the time in between frames would make it wither lighter or darker.

On the other hand, if there was sludge on the rollers, it would overdevelop only parts of the image.

so if its not the negs and then the scans might be dodgy............I don't think its light leak

cheers

Good find!
This really deserves a link on the resources forum.

Definitely an X-Ray problem in my sense. Just look at the bottom of the page for full size scans of exposed film without any images. They show the same pattern as on your images.

See the CTX 5500 Exposure 45° exposure inside core sample.
