Back to Film Making

[Mark Osterman]

So, I have actually been making the 1925 era film since this time last year but I'm only now navigating the Photrio forum once again. Anyone interested?

 

[brazile]

Yes, please!

 

[david schaller]

Definitely! Thanks for offering to share.

Yeah, you bet!
For those curious about the background, here's a link to the earlier threads on what I assume is ultimately the same project/journey:

Making 1925 Gelatin Emulsion and Coating Film for 1925-2025 Leica Centnnial

Not sure if this forum is interested but I am currently creating new 35 mm film with a 1925 era ISO 12 blue sensitive film for shooting in a 1928 Leica I camera. This also has an anti-halation coating on the back. It is based on a roll of film shot by Oscar Barnack in 1914 that I currently have...

My newly made MO-1925 era Film

Never quite sure where to post this sort of thing. Please let me know if there is a better place. I’ve been working on a Leica Centennial Project of making the same type of film that would have been available when the Leica camera was introduced. Three weeks ago I made a run that is about where...

Yes! I have also been following you on FB...

Please

 

[Patrick Robert James]

Yup

 

[Daniel Stuefer]

Always! =D

 

[bdial]

Absolutely

As an engineer, really interested to see the process! Did you make the coating machine yourself, are more people diy-ing this type of equipment?

 

[Ian Grant]

As a former photo-chemist and emulsion maker (for an applied use), I'm interested in what you are doing.

There you go, all disciplines available, let's recreate that 3200iso colour negative film

Only if it's Kodachrome.

Very interesting. Many years ago, I shot 16mm fine grain positive print stock in camera at about ei2. It was the only film I could afford. Had I known to soak it in sulfur, I could have gained speed. Another approach would be getting fine grained positive 35mm prnt stock, sulfur or ortho sensitizing, than applying the dye for anti halation. This would be technically easier for most and likely less expensive?

My question on this would be what is the cost? I played with making film plates many years ago, but it was difficult and the materials were very expensive, so I gave up on it. Probably many have tried this.
In your case, the experience is what you're looking for, not money saving. But with high film costs today inching up rapidly due to inflation, this on some people's minds.

Hi Mark,

The 1920's were such a remarkable time for the emerging analog technologies that helped shape the rest of the century... radio, photography, automobiles... Now, 100 years later, everything's digital and happens instantly with just the swipe of a finger, but our increasing detachment from physical processes makes the old ways of making and doing things very interesting to inquiring minds.

For handmade 35mm film, the perforating seems to be a big hangup. Are there any readily available devices that will do the job for DIY film folks?

Further discussion can occur in this thread where @Mark Osterman has shared some really nice examples of the project: https://www.photrio.com/forum/threads/home-made-35-mm-film.219410/
