Russian film tests
Anybody wanna discuss film?
This website shows results of film testing by a Russian institute: http://filmscan.ru/articles/article07.html I deleted all the discontinued films sorted results by resolution, then tested ISO. Your choice of text or spreadsheet. http://cacreeks.com/filmscanRU.txt http://cacreeks.com/filmscanRU.xls Comments? |

I had tried it when it first came out, and it was a little fuzzy. But the roll I picked up a few months ago, gave me impressive results. BTW, Portra400 is my choice for a very good 400 speed film.

Looking at the XP2 and the BW400CB, I can't help but wonder how they would compare at the same exposed ISO? I think the table is being generous with Velvia100F. What is ProPhoto400BW? Was there an explanation of rational behind the "wild" ISO testing, some over, some under? Thanks for the tables, Jim |

It's not clear to me whether usable stops and resolution are measured at the box-speed rating, or at the actual film ISO. I think the table is being generous with Velvia100F. That's probably a discontinued film now, or nearly so, but unfortunately the Russian institute didn't test new Velvia 100. Do you think they're being generous with What is ProPhoto400BW? I'm not certain, but I believe it's similar to discontinued Portra 400BW. Was there an explanation of rational behind the "wild" ISO testing, some over, some under? Yes-- most films are not accurately rated. There are various categories expected in certain markets, and depending on what the chemistry yields, manufacturers provide product in these categories. The most infamous example was old NPH, which was really a 200 speed film. A less famous example is Kodak 100UC, which is faster than 100 speed, and probably very similar (or the same) as Elitecolor 200 in Europe. New Portra 800 seems faster than 800 to me. That's one of the films that was revised since this testing. Others are the new Portra 160/400s just appearing. |
