Ilford Dufaycolor

[GregW]

I realize this is the BW forum, but since the process is based on BW processing...Anyway, I've come across a roll of unexposed Dufaycolor from 1937. It's 116 format. I've found an old set of processing directions online. using MQ developer and reversal processing the roll. Dufaycolor is a color matrix with bw emulsion that gets reversal processing. It essentially a slide film. The plan is to locate a Kodak 1A in good condition and shoot it and process. Then if results aren't too great, explore the idea of stripping and recoating it with liquid light or? Does anyone have any experience shooting an old roll of this? The asa was originally 10. so i expect it is even slower than that now. Is it possible to strip emulsion from the base after it's been developed? There is a layer of varnish between the emulsion and the reseau.

a good article on Dufaycolor with processing info:

This film is probably more valuable as a collectors item than for any results it can now produce.

I agree with Gerald, I'd keep the film as a collectable. Our school photo club was given some outdated Dufaycolor in the 1960's, and, with the help of the chemistry teacher and the official "Dufaycolor formulae book", we shot and processed some rolls. The film worked, but the colours were dull, and the emulsion was very delicate, I can remember one film where the pictures floated off in the wash water! Interesting exercise then, but I think it would be a waste of time 50 years on!

I used some 'Dufaycolor' in the 1950's in my Ensign Selfix 16-on camera -- if you were lucky you got a 'fast' batch of 8 ASA -- I got 6 ASA and a gelatine Cyan filter -- my Mum took one of me in my Scout Uniform and I scanned it -- not all the full frame was there as it had bee cut down to a square format ----

Pretty amazing! My Dad took Dufaycolor on their honeymoon in 1938. He developed and hand mounted the slides. They have faded a bit, but are still interesting.

Nice photo, Love the colors. I'll keep the packaging for my collection, but have wanted to experiment with this color process for a while.
