    I've been wondering what to do about the loss of R3000 chemistry. In the most recent issue of Photo Techniques magazine (Sept/Oct 2002, p. 18) Robert Chapman lays out the ingredients and approximate ranges (in grams) of each, but doesn't know the exact formulation. Instead he proposes an experimental method for making up differring concentrations of each component in each developer for testing.

    Now, this seems like a lot of work, runnign through all those different formulations of each developer and blix (a total of 36 different formulations that he includes in tables), way too much for one guy to experiment with.

    I was wondering if some of us R3000/R3 guys might want to team up and handle the job in parts. Currently I have an almost full 12.5/25 gallon R3 kit, and I can use the kit components for two of the chems, while experimenting with the home-made third chem (for example, I might concentrate on the first developer, while using the color dev and blix from the kit) and someone else might concentrate on the color dev (you might still be able to pick up the R3000 first dev and blix from B&H) while a third fellow concentrates on the blix.

    I'm not exactly sure how to assess each batch (I guess color test strips from Kodak, but we'd need a color checker or Macbeth chart reader of some kind to quantitate the results).

    The risk of spending too much effort on this is, of course, that Kodak and Fuji will stop producing color reversal papers and leave us with Ilfochrome or internegs.

    I'd be interested in cracking the formula, but just don't have the time right now. Any idea why all the different R-3000 type kits have dissappeared from the U.S. market? Is it a shipping issue or a market (i.e., digital) issue? I know that Freestyle still has a version of the R-3000 kit under their Arista brand, but they can't ship it. Tetenal's seems to be available in Europe, and I've also seen another European kit that involves buying an R-4 kit of a certain brand and combining it with their second developer for reversal processing. Of course none of it seems to be shippable to the U.S.

    Good news!

    Freestyle in their latest catalogue states that changes in shipping regulations now allow them to ship their Arista R-3000-like reversal print kit by ground with no hazmat fee.

    Any sign of the other R-3000-type kits returning? What's the status of Fuji Type-35? Is it really discontinued, or was that an unfounded internet rumour? I'm not that enthusiastic about Kodak Radiance. Anyone tried the Agfa reversal paper?

    That is good news! I've never used Arista's chems (Kodak R3000 and R3 only), but availability of any reversal chemistry is good.

    Last I heard, Type-35 on paper is discontinued, but the printing material (polyester) is continuing. I can't remember who told me this, so it might be rumor. I know that Type-35 mates well with Fuji films (and the new Kodak 100 films), but have never tested to see if Kodak film works as well with Radiance. Fuji film and Radiance are not friends.

    I've had good luck with the big R3 kits, and have the reversal exposure figured out (first dev, quick rinse, stop, dismount tube, use a fluorescent shop light for the exposure, remount, rinse, and continue). Storage of color dev part B is the only tricky part of slowly using the 12.5 Gal kits ( I use 40 mL teflon-sealed sample vials, 100 for $60 from Fishersci.com, 40 mL is just enough to make 1L of color dev each).
