It's like Yeti, known to many, but rarely seen.

Great accident. I've only once had them in almost epidemic shape - but none falling as decoratively into the image. In my case probably a combination of something omitted in the production of a Ektachrome batch with the RZ67 motor drive spooling on faster than common for 120. But it seems to be a widespread issue in aerial photography, where it is quite common for the air humidity to drop to positively unhealthy levels.

That guy must have some kind of ion plasma drive.
I get static marks loading 120 film onto the stainless reels. They look like new-moon shapes.

what he said .... yetis also have a lot of trouble with reticulation, and refraction is an endless headache too

I couldn't believe my luck! Once in 40+ years! The discharge is double-ended, and effectively symmetrical, but the other end (in the next 14x21mm frame) was nothing like as beautifully placed. It was, of course, a cold, dry day.
As for Rob-F, I'm pretty sure that what you are describing are not static marks, but stress or pressure marks from bending. They're quite easy to replicate.
Cheers,

Yep, I have had both. I think the last (maybe only) static discharge was in Korea in the 74-76 time frame. I got more careful after that. It seems most likely to occur when re-winding fast in very cold dry times.
Pressure marks I only got once also (at least on other than the reel end). I try to learn from my mistakes (and I have learned a lot).

Like many problems they have been addressed by the film vendors. Some early polyester stocks were particularly "evil". Most modern films these days have on their bases an anti-static treatment.
A combination, I'd guess, of motor drive, plastic cartridges, the felt used and film without an anti-static..

One roll, in one camera (Nikon Fm2n), on a cold day in antarctica was badly struck (6 or 7 frames ruined). Never before or since.

Actually I don't think that is static, looks more like an early version of a Pink Floyd cover to me

While I haven't seen it in some time, static used to be quite common when using a motor drives in Alberta's dry climate. You can see the static discharge in the lower left-hand corner.

I never had that kind of luck with static electricity and photography. Though I'm often victim of it myself on dry cold days.
Worst experience: Turning on a machine in the office and getting a massive static shock through my right hand, and spilling hot coffee over the other hand as a result. 🙁

I had one roll of Tri-X covered in small static marks back in 1984 or so. Multiple frames, nearly the whole roll.

Only once, long ago. I got streaks along several negatives, similar to Rogers example. I rewound my M6 just as fast as I could and that caused the streaking. Another reason to like my M3 rewind knob. Joe
