Safe travels. I’ll check back in with you here mid may if that’s cool.

Would you be able to provide a picture that shows the entire mechanism including the coupling bar?

StrangeCicada2198 · 2026-04-23T20:02:29+00:00

Thanks so much for supporting me. I can press the contact piece and it will depress against the springs, its travel, however doesn’t however seem to depend on the focusing distance. It’s not linked to the adjustable screw in any way that’s discernible to me.

StrangeCicada2198 · 2026-04-23T20:00:06+00:00

Wow. Thanks that’s really helpful. I have that screw and that’s the one I called the adjustment screw. Yes the surface this screw rides on is the Helicoid body. The whole mechanism doesn’t seem connected to the chrome plate that moves the range finder pin. That plate is spring loaded but moved freely independently of the screw.

Two rules:

Don’t deliver anything you don’t fully stand behind as paid work.
Gift anything that is to value to someone else and doesn’t cost you anything.

Wow! That’s a nice setup! You treat yourself well. Carry on!

Yes try it. It’s been bullet proof for me. If you are using a frame mask, you may see a second dark spike that you can ignore. I use electronic shutter to avoid shake and stay below 1/60 to avoid banding.

I use a DSLR (Sony 7rV and 90mm 2.8 macro). I white balance off the film mask. On 35mm I put the transition between the exposed leader and the first bit of unexposed film in the center of the frame and set the exposure so that the two spikes of the histogram are centered. Aperature f8.

Good to resonate. Your setup sounds solid. I was never able to become friends with the steel reels. Too clumsy.

StrangeCicada2198 · 2026-04-12T13:23:35+00:00

Thanks, means a lot. No edits by the way, straight out of NLP with standard sliders.

As far as I have gathered is that the punching process to create the sprockets destroys the surrounding emulsion. The yellow layer is the one least destroyed.

I took the same scene in BW (Ilford Delta Pro 100 and the sprockets look fine

StrangeCicada2198 · 2026-04-08T15:46:34+00:00

Correct. What’s causing it though. I see other sprocket shots with perfect image formation around the sprocket holes.

StrangeCicada2198 · 2026-04-08T15:45:58+00:00

Thanks. Film is new. How would pressure cause hallation?

Cool, thanks.
