wrote: 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 You are correct in all of the above information of course. I have 20 rolls of 120 left and 2 children to shoot them on. IMO APX25 was simply the most beautiful film ever produced. I found Zone VI's PQ developer to work great with it. As far as Tech Pan, I really like the Formularies (Bill Troops') TD-3 developer.

That's Foy's site and he just told you that the film's supposed to be an Agfa product. He might be spooling from bulk rolls in Canada. That would make more sense.

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 Not sure whether this post is actually from David Foy, given the fact that there's no real name on the post. If it is, he should have remembered what he posted on photo.net in October, 2003: http://www.photo.net/bboard/q-and-a-...?msg_id=004JAv David Foy , oct 08, 2003; 10:45 a.m. Disclaimer: I am the person who makes and sells these products. "Bluefire Police" film is a microfilm, Tura Pan Line, made and packaged in Germany. "Bluefire HR" developer is based on the H&W Control formula, as disclosed in the patent, functionally identical but slightly modified for longer package life. It gives similar results with Fuji Super HR and Agfa Copex Rapid Pan AHU (which was the original H&W film). The rating of EI 80 is realistic. The Bluefire film/developer combination compares favorably with the only other similar film/developer combination widely available today, which is Kodak Technical Pan and Technidol developer, which is most often shot at about EI 25. Manufacture and marketing of the Bluefire products is now in the hands of Adox Fotowerke, Inc., who will give them wider distribution. The Adox Fotowerke web site (http://www.adox.net) does not yet have information available as of this date (early October 2003). David Foy I certainly hope this helps to clear up any confusion. --Greg -------------------------------------------------------------- Greg Mikol This email address is registered with the Washington State Attorney General's office and WAISP.

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.

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. Well, I'm not Mr. Foy, nor do I sell any film, but FWIW: Films like Gigabit or Bluefire are, to my knowlege, based on microfilm emulsions like Agfa Copex Rapid, as mentioned by Mr. Foy. Microfilm is manufactured only in a few standard-sizes: 16mm unperforated 35mm unperforated 35mm perforated 105mm unperf (?). and 105mm x 148mm - Fiche. Copex Rapid is Agfas "fast" microfilm, and is only available in 16 and 35mm. So the only possibility to get Copex Rapid (and therefor Gigabit and other products based on it) in 120 would be to special order this emulsion by Agfa, which would be $$$ and the minimum order is huge. This is most propably the reason why Gigabit sheet-film is another emulsion than the 35mm perf. Agfa offers a "medium" speed microfilm - Agfa Copex HDP - which is said to have even finer grain as Copex Rapid, but is much slower. Copex HDP however is sold in 105mmx61m rolls. So here it may be possible to cut size 120 (which is about 61mm wide). And you would have some leftover to cut 127 or 16mm or Minox size from. I don't think this would be an option as the result would be much slower than Gigabit or Bluefire, I would guess about ASA 20... or less.
