[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Jim, It might help to use EV. My Gossen chart equates 16 footcandles to an EV of 5. If the data sheet doesn't mention an aperture then it will truly by a guess and by golly. At an ISO of 6 then at an EV of 5 you get 8 seconds at F16. That would translate into 1/4 at F2.8. It would be interesting to see a lens that has both an ability to cover 11X14 and a maximum aperture of F2.8 Hope this helps.

It's usually used as a "contact print" film to make color negatives of positive slides. I found a couple of boxes of it and want to try it with the Korona 11x14 outdoors but have no idea of the film speed. A data sheet recommends a (3200 K) light source with exposure times of ? second to 8 seconds with most at 1 to 4 seconds.. Illumination level at the exposure plane to 16 footcandles (172 lux). Does anyone know what this might amount to in ASA/ISO? I'm guessing about ASA 5-8. Thanks in advance, Jim _______________________________________________ Leica Users Group.
