Idea for Tray processing

Ian Grant · Jul 3, 2010

Came across this in my ancient Agfa Photo-Handbuch, written by Dr. M. Andresen of Rodinal fame.

Could be made/adapted for a variety of uses but the beauty is no need to handle wet film in the dark in dishes. Some pegs to hold 4 sheets of 5x4, or 2 7x5's, could be very versatile.

Even better for wet plates, home coated plates etc

Ian a direct translation is:- "developing hanger"

My late father in-law (German) had some pictures of these in his photographic books and apparently used them pre WWII as a young lab rat.

Given the inherent springiness of sheets and the amount of lifting required between the trays (and the film falling off/out of the hanger) I'd suggest sloshers as being more practical these days. You can do four sheets of 4x5 in a 12x10 tray, for example.

I was born with 2 sets of hangers, called hands.:rolleyes:

I can't see how a sheet of film could fall out of the original hangers.
There are recesses on the hangers and when inserted they are under tension.

Ohhh, so the flat part in the photo is the film ? That could explain it. I thought it looked a bit too 'optimistic' to use it as a simple bed for the film, presumably with the film slid under a clip of some sort to stop it floating off. With the sloshers I've seen the film is trapped under plastic-screw heads to hold it down, and that works fine.

The image shows a hanger for glass plates, but if you used a piece of PVC or polypropylene sheet you could easily fit pegs to locate film securely, and instead of wire use plastic (heat) welding rod. I have rotating plastic pegs sold for the backs of picture frames which would work perfectly.

My reason for posting the image is this is such a simple but adaptable idea.

No, Ian, it says in the ad that it is for films.
And that the kit contains the hangers and a puncher.

Well you know I can't speak German Thanks for clearing that up.

I'd rather not punch holes in my negatives but will be looking at possible adaptations for 10x8 film processing, and it would work well for glass plates.
