Film prices, the good old days

You have to be careful using winders. In dry weather film can build up static electricity and cause streaks and flashes on the film. I’ve had it happen before in the darkroom. You can actually see it happening.

A company I worked for in the early 70’s had a bunch of Hasselblad EL’s with 70mm backs. During very cold dry weather the cameras transported film fast enough to build up static and cause lightning flashes which ruined your film. It actually looks like bolts of lightning on the film when you process it.

Yes, the black plastic bags spark as well.

That's one reason Vision 3 has remjet, to eliminate the effect of static electricity in 24fps movie cameras. Don't think I would be capable of manually rewinding at that speed!

24fps isn’t feet per second, it’s frames per second. I did a lot of cine work in both 16 & 35 mm so I’m quite familiar with that. 35mm at 24fps runs roughly 90’ of film through the camera in one minute. Not terribly fast.

Im very familiar with remjet backing and static marks are still possible with it. On several occasions I’ve had small labs ruin film when rewinding it too quickly in prep for processing.

Well yes, 24 feet per second would be a whopping 16 seconds of footage on a 400 foot roll. I thought it was self-evident than 24fps referred to frames.

Even rolling 24fps working blindly in a changing bag, don't think I'm going to achieve that. It's not a race! lol

When I worked for the DOE in the mid 70’s we did ultra high speed motion picture. We used a 400 ft model Redlake Hicam and shot 16mm film up to 44,000 fps. We used FF33 flash bulbs to light the subjects but regular #3 bulbs could be used because the shutter speed at 44,000 fps was 1/100,000 of a second and 400 ft of film went through the camera in 1/10 of a second. Yes what took 11 minutes to project at 24fps went through the camera in 1/10 of a second. NASA had a classified camera at the time that they used to study rocket engine ignition that shot 150,000 fps.

Often what we were studying only occurred in a half dozen frames or so. Now the Redlake is a toy with much faster digital cameras. But at the time the Redlake was pretty amazing.

I would say even today it is!

My "good old days" were in the 1970's. We had Freestyle in LA with Ilford 100 foot rolls for $5.69, then we had Bona-Fide Novelities and Fairstryk in NYC with outdated film like aero Plus-X for $3.50 at hundred feet and Tri-X and 4X for $4.00 a hundred fool roll, 2750 for $.3.75 for a 125 foot roll.

Those were the good old days!

I have only one 100' spool. Wish I had saved others...

Could 100 feet be spooled onto that, and the remaining 300 left for later?

Sorry for the dumb questions, but what's a core vs a spool?

A core is just the middle part. A spool has sides that keep the film in place. At least that is what I call them.

Sure. Unspool what you want and put the rest back in the can.

Yeah, when I am loading the smaller spool I keep one hand on the spool in case there is any static. Haven't had any issues yet.
