C-22 Process

I gained 30 rolls of Kodakolor X negative film, and use some rolls in
my Rolleiflex, but this film are developed in the C-22 process, and i
have no idea how to develop.
Somebody knows some alternative developing process for this film?

Thanks

I'm going to hope/assume this 30-year-old film has been frozen or
refrigerated, and that you're not planning on shooting any more of it.

While it probably possible to do some sort of B&W development at home,
you're far better off with one of the few remaining labs that can do
C-22. For example, try:

Tanks for the help

but I intend to develop the negative in my darkroom.
I already elaborate an alternative process for the ECN-2 (cinema),
and I go to try using fenidone developers (D-76) and Metol (ID-11)
If i have no sucess in none of these processes, I go to try to use
LOOR developer from Kodak, being varied the temperatures and times

So.....

Lets have some fun in the darkroom

Good luck to you.

I can't help but be curious; what is the purpose of this
experimentation? It can't be good pictures, as you have no chance of
that; it can't be to develop a useful darkroom technique, as there
won't be anymore Kodacolor X.

In the late 1990s, I think I published the formulae and process in this
newsgroup. I just now tried to retrieve it, but Google said that the archive is
temporarily not available.

If you cannot retrieve it from the archives, send me an email and I will scan
the page from the British Journal of Photography, whence I got it, and email you
the formulae and process.

The purpouse is only experimental.
I have no idea on what waiting of the developing.
My hobby is to buy lots of old films to "make myself" dead processes,
like C-22 and ECN-2

Hi Francis

If you have the formulae, i will try to make it at home.
Maybe the old reagents have some difficult to find, but i can study
and make some adaptations.

I´ll look at the archives.

Tanks a lot

A citation I found for substitute formulas is The 1965
BJP Annual pages 263-264. Some of the reagents, in
particular the color developing agents, may not be available
now. The British Journal Almanack is not too difficult to
find, larger library systems will have it. I did not search
for on-line editions but try the new Google books search.
BTW, D-76 is _not_ a Phenidone developer, its Metol and
Hydroquinone.
In general, its possible to process older color films to
B&W silver negatives. They will have a "stain" because the
remaining color couplers are themselves colored, a way of
producing an automatic color correction mask. The dye can be
bleached out but once you do that the negatives can never be
redeveloped for color.
B&W development can be done in any standard B&W developer
but you will have to experiment to find the best times.
