I just bought a cheap old 16mm 30m/100ft Kodachrome 25 (expired in 1988) to practice film loading with my new Krasnogorsk-3.
But since this film came still in its original packaging, I thought of actually shooting some short clips with parts of it as well to further test the K-3 before buying fresh film.
I don't have any Lomo tanks for 50/100ft developing at hand but thought of using Paterson photo reels for the clip tests.
What about the following experiment:
1.) In the darkroom cut off a 5ft piece of the 16mm film and load on a 16mm movie daylight spool
2.) Shoot these 8 seconds at 24fps with the K-3
3.) Unload in the darkroom and tape the 5ft 16mm film to some junk 35mm 5ft film, emulsion facing out
4.) Load that bi-packed film as usual onto a Paterson 35mm reel for photo developing
5.) Do remjet removal then develop as a black and white negative film
What do you think? Any chance this could work at all?
I see a problem with the film's speed, let's assume it lost 1 stop per decade, so it's at ISO 3 now (25 to 12 to 6 to 3).
The camera uses 1/60s at 24fps and the lens starts at f1.9, so I played around with the "sunny 16" rule, correct me if I'm wrong;
With ISO 3, on a sunny day, I shall use f16 and 1/3s.
f16 down to f1.9 is a bit more than 6 stops, so on a bright day at f1.9, I overexpose by 6 stops at 1/3s.
So my shutter speed could go faster, 1/3s to 1/6s, 1/12s, 1/24s, 1/48s, 1/96s to finally 1/192s.
So wouldn't that mean I can use 1/60s at 24fps with that ISO 3 and have enough light still?
Otherwise I could still try to use 8fps, which uses 1/20s to let in more light.
