The cyan filter will really do nothing at all. ST8 is orthochromatic, so it's already biased strongly toward the blue. The problem with printing color materials to an ortho print stock (aside from the weird color rendition that you get in the print) is that the yellow mask on the negative means you have to increase the exposure a lot. If you look at the datasheet for ST8, it has a .5 density for 0 log exposure, a density of 3 for 1 log exposure. So you're wanting to keep exposure within that range. > Then i applied to PF2, the same negative, same filters. > The result for PF2 print was totally clear. Nothing exposed. If you look at the datasheet for PF2, to get a .5 density you need a 2 log exposure, and to get a density of 3 you need a 3 log exposure. So you need to expose the film about 100 times more strongly than you do ST8. >Is there any way to print color negative film on Orwo PF2 stocks? Run the printer 100 times slower or open the iris 7 stops. --scott _______________________________________________ FrameWorks mailing list [email protected] https://mailman-mail5.webfaction.com/listinfo/frameworks
