Infrared film with uncoated lenses

I want to try Kodak HIE (I have a few rolls left) with uncoated lenses. I think it might be impossible to load the film in complete darkness - a requirement - into a screw mount or M-mount Leica. The alternative would seem to be some sort of adapter to allow Leica lenses to be fitted to a SLR but I understand that these only exist in association with the Visoflex and so one is limited to close-focusing and/or longer focal length lenses.

 

- any ideas?

Learn how to load the camera in complete darkness.

Thank you Zapp. Prior to processing, HIE can only be handled in total darkness. It is, indeed, possible to load any type of Leica in complete darkness. I was really thinking more in terms of the requirement to trim the leader when using Barnack models. All of which suggests using M-type bodies with a screw-mount adapter.

Loading a Leica in the dark is no worse than loading a developing tank. It just takes a bit of practice with a sacrificial roll of (non-IR) film.

 

Trimming the leader for a screw-mount camera in total darkness is a bit more difficult unless you have the template (ABLON?) that Leitz sold for just that purpose.

 

Again, practice makes perfect. If the film is in a Kodak cassette I expect it would be possible to trim the leader safely in a very dim green light - e.g. a Kodak #3, intended for developing panchromatic film by inspection. Better yet, get hold of a Leica reloadable cassette and (in total darkness) open the Kodak cassette and transfer the film and spool into the Leica one. Being all-metal the latter should block IR light and make it possible to trim the leader safely in subdued room lighting.

 

Good luck!

Thanks, John. Actually, I've just hit on the idea of using a second-hand Bessa L (or is that blasphemy in the context of this site?) now all I need is some means of fitting a red filter to 50mm and 90mm Elmars and a 35mm Summaron......
