developing Macophot ortho

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

Has anyone tried developing (Cachet) Macophot Ortho for continuous tone? I found the best results were Rodinal 1:50 exposed at 25 for 6 minutes. But the results are still very contrasty. Has anyone tried technidol? Cachet recommends something called Docufine HC, but it is not available in the USA.

I want to know this also! :-)

I forgot to mention the unsurpassed grainlessness of the film. Tech Pan looks coarse in comparison. Also the recommended developer is Docufine LC, not HC as I initially stated.

Have you tried Rodinal 1+200 or 1+300? I have tried Technidol with lith-film with bad result. Highly diluted Rodinal worked best.

I plan to try rodinal further diluted although I found no discernible improvement with it at 1:100 for 9 minutes. I will post the results once I have completed them.

Have you tried a pyro developer. People are getting great results with PMK and is the basis of enlarged negatives for platimum prints.

Thank you for your suggestions. I have been avoiding Pyro because it is so toxic, both to the user and to downstream inhabitants. Has anyone tried Photographer's Formulary's POTA developer?

I've developed lith film with good luck using two developers - D23 diluted 1:3 and a variant of T/O XDR-4 published by Anchell and Troop called TDLC-3. D23 stock utilizes 7.5 gms of metol and 100gms of sulfite in 1 litre of water. TDLC-3 utilizes 1 gm of metol, 5 gms of sulfite and 10gms of sodium bicarbonate in a litre of water. POTA should work well with these kinds of films (althought I've heard people complain about streaking). Good luck, DJ.

If you are avoiding pyrogallol, send me an e mail if you like a formula using pyrocatechin, which is not as toxic as pyrogallol and is used in such small amounts is unlikely to damage the enviroment once is disposed off and diluted. I am getting great results, both in regular film and ortho negs.
