Agfapan 25
I'm still reeling from the Kodak Tech Pan decision as I'm sure many of
you are. 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 |

Donald is an highly reliable source, but this information is not correct.
Yes, Minopan 25 is Agfapan 25. But it is not a microfilm. Although Agfa discontinued their Agfapan 25 film about two years ago, Minox has a considerable stockpile and will probably continue offering Minopan 25 for years. It is processed in standard developers like Rodinal, D-76, etc. It is not a substitute for Technical Pan since it is much grainier. Tech Pan is, in essence, a microfilm, albiet a modified one, which is why it needs special development. Agfa will not re-commence making Agfapan 25. The best substitute for it is Maco UP25, which should continue to be available for the forseeable future. The other films mentioned (Copex and Bluefire Police) are microfilms which must be processed in an extremely soft developer in order to achieve pictorial contrast. Both are less grainy than TMax 100, which is currently the low-grain champ of the standard film world, and both have more conventional tonalities when correctly processed. As Donald noted, 35mm Gigabit is Copex Rapid Pan AHU. Gigabit in sheet film sizes is a different Agfa microfilm. Bluefire Police is often said to be Copex Rapid Pan AHU, but it is not. When given identical exposure in a sensitometer, and processed together in Bluefire HR developer, they develop quite differently. In twelve minutes of continuous agitation, Copex develops to gamma 0.33, while Bluefire Police develops to gamma 0.48. Copex has a more abrupt shoulder, Bluefire Police a more abrupt toe. Their speeds are about the same, but Bluefire Police is a little faster. The emulsion colors of the two films are noticeably different. I have tried to find out what Bluefire Police is, but I have only been told is an Agfa microfilm not available outside Europe. Nothing more specific.

David Foy http://www.bluefire.ca Mr. Foy, Any possibility we might see either of these microfilm products on a 120 spool? Bear in mind that the existing stocks of Tech Pan are due to exhaust in the next six months. |
