It is microfilm ( very high contrast). What do you want it to do?

Since we have been making this formula and its predicessor, F 60 Film Developer, for thirty years, Ilfords DD-X is very similar to our formula. It is a phenidone HQ formula and does not resemble the Metol HQ formula of KODAK D76. It is much more sophisticated in design and purpose than that 1920s fo...

It does sound like you are not getting enough chemical movement in the process. You are correct, five minutes is at least twice enough time to fix the film. Use a slightly smaller volume of chemistry and see if you get a better result.

kieth, i can get it there someone needs to order it.

Kieth: Why?

Yes you can change dilutions and times to acheive different results, push, pull, extended processing times, and changes in contrast. I can email to you additional information.

Hello Gary F 76PLus is not like D 76. F 76 is a phenidone based developer. It is a compensating, fine grain developer. A Gamma One developer provides the widest latitude for processing. Gamma is defined by the longest straight line section of the standard curve. Gamma one is a 45º line originating f...

I think you are confused about DTR (Copy Proof). It is no longer available, not at Freestyle or anywhere in a usable format. Any supply of that film or paper are so far out of date to be fogged beyond any use. There were a variety of ACTIVATORS (negative) and DEVELOPERS (postitive) that used to be a...

Diffusion Transfer is no longer a vialbe system. There is no paper or film available for years, any inventory that you may have is so far out of date as to be unusable. While i can make the chemical i don't think you want to meet the minimum order i would require to make it. You can call me if you w...

FIRST Developers do not increase grain size they reduce it, disolving the smaller grains leaving the larger ones just smaller.

SECOND Develop the film as if it were PAN F, dilute 1+14 and develop for 5½ minutes as a starting point.

We private labeled most of the DEFENDER CHEMICALS. i believe that product to be our P20 Developer.

PHOTOTHERM RECOMMENDS OUR f 76 DEVELOPER WITH THEIR EQUIPMENT. I HAVE DILUTIONS AND PROCESSING TIMES FOR THE VARIOUS FILMS.

If you use Clayton F 76 plus Developer with Delta 3200, exposed @1600, dilute 1+9 and develop for 13.5 minutes. The results will be outstanding!

Your first test should be with the times and temps the came as LC 29 with Delta 3200. Look at the result and adjust your processing time accordingly.

The reason for the differences in dilution is that we write the CLAYTON label for machine processing and the ARISTA PREMIUM COLD TONE label is written for hand processing. As for the difference between acid and alkaline pH in fixers, it is much a do about nothing. The capacity of the fixer is based ...
