ORWO b&w film?

I'm not trying to challenge the claim, just get solid information rather than Usenet hearsay. As for the news references, you'll need to find the actual references yourself. I remember stories about it in Shutterbug, Photo Techniques and -- perhaps, but I'm not certain -- in Pop Photo. If the information was published in photo magazines then it's probably reliable. FWIW, I did some digging and found a few Usenet and other forum posts about this dating back as early as 1997, but they're all lacking detail and attribution. Generally there is a lot of doubt about t/delta grain in films outside the big three (Kodak, Ilford, Fuji) because of the multitude of patents and expensive R&D which would be difficult to recoup because of low sales, etc. Concerning patents, Kodak T-grain films date back to at least 1988 (T-Max 3200; http://www.kodak.com/US/en/corp/koda...980_1989.shtml). That means that the basic T-grain patents are likely to be at least this old, which in turn means they've probably already expired. (Patents issued in the US at that time lasted for 17 years.) I haven't actually done a patent search, though. -- Rod Smith, http://www.rodsbooks.com Author of books on Linux, FreeBSD, and networking |

ORWO b&w film?
nailer wrote: many years ago I wedded very nice girl (then). All my photos were taken on Agfacolor 80S, Agfachrome 50S and Ilford HP5 or HP4, can't remember. Deliberately I rejected Ektachromes and Kodacolor films. The reason - MUCH better results. I have been comparative-testing materials since 1968 or so. I have used all the major brands (Adox, Ilford, Fuji, Kodak, Agfa, Ansco, dPont, Tetenal, Paterson, Plymouth-Ethol, etc.) of films, papers, and developers. Ilford HP4 was inferior to Tri-X. HP5, when it came out in 1979 or so, was a huge improvement over HP4. I switched from Tri-X to HP5 at that time, even though I had used HP4 sporadically despite its inferiority to Tri-X. Agfa papers, but not their films, have been available in the US for decades. One can only surmise that their films were not competitive with Kodak's. That was confirmed for me when I tried the new 'improved' APX 400 last year. It was not even close to Tri-X. In fact, APX 400 is horribly grainy. It looks like a 1950s-era film, at best. Although I never used Portriga Rapid, I was never able to get decent prints with Brovira. duPont, Kodak, and Ilford papers were very similar, but not rovira. Something about its curve made it impossible for me to get highlight detail with negatives that printed just fine with other papers. Rodinal is crap. On Tue, 7 Mar 2006 17:10:37 +0100, (Ralf R.
