I've been doing a small stocking up but of course an alternative would be better than stuffing my freezer with film. I've seen that Agfa makes a 25 speed B&W film for the Minox format. If this film were to be produced in 35mm and/or 120, how good of a substitute would it be for Tech Pan. Also, is it any good to begin with? Thanks There simply is no substitute for Tech Pan. There is no film that is it's equal. No conventional film can match the granularity of Tech Pan. Tech Pan, as opposed to other pictorial films, had an emulsion composed of silver halide crystals nearly all the same size. This is what gave it both it's exceptionally fine grain and high contrast characteristics. A POTA developer was thus the only developer that could produce normal contrast. APX 25 was a good film, but also grainier, since as a conventional pictorial film it contained a mix of both larger and small crystals. A t-grain film is probably about as close as you'll come, but can't equal Tech Pan. Frankly, I'm not looking for a film with the same "look" as Tech Pan, but just with the same granularity. I'm sure Kodak could make a T-Max 25 if they wanted to, but they're not about to do that, so I have to scrounge around other makes to find something similar. TMX to me has visibly more grain than Tech Pan . I've always used it with rodinal, which isn't exactly a fine grained developer. But the t grain still remains pretty fine in large format. D76 or Microdol-X should give pretty fine grain with TMX 35mm. |

The best substitute for it is Maco UP25, which should continue to be available for the forseeable future. Efke 25 isn't bad, either. Maco 25 and Efke 25 are the same film made in Croatia by Fotokemika. Efke packages their 25 film for Maco in Maco boxes at their factory. In addition, Maco UP64+ is Efke 50 and Maco UP100+ is Efke 100. Maco has no coating facilities, all of their films and papers are made by other firms. The Maco Infrared, Ort 25, PO100, TP64, and Genius films are also made for them by Fotokemika (Efke). |
