Well, guess you did throw me a curve ball in that case! I have quite a selection of misc rolls of film in my freezer simply for sake of nostalgia : Kodachrome 120, Konica misc, maybe some old Agfachromes (loved 120 Agfa 1000) - none of it any good anymore. I do remember the old Ektar 25 version with its very serious crossover errors. The most color-neutral film I have ever found was Astia 100F; I used that in 8x10 for duplicate chrome work; it was even better than Fuji CDUIII, which was basically tungsten-balanced previous Astia, and
even better than Kodak EDupe. But I found it less versatile for general shooting than E100G, which the current E100 seems to be a minor improvement of, but still not as evenly balanced as Astia; in other words, it wouldn't pass the litmus test as a highly accurate duplicating film. But after a lot of time and money, with the color neg improvement in 160VC being a stepping stone, I'm figuring out how to get the most out of Ektar as a taking film worthy to replace many (not all) chrome film niches, as how to turn Portra 160 into an excellent interneg film for making my previous chrome work printable on current RA4 papers, but that involves either masking or using an already extant dupe with all the contrast correction variables already built-in. The only thing certain is that the era of Cibachrome has ended, and once I saw that writing on the wall, I knew I had to figure out how to get color neg film into territory well above its traditional stereotypical applications, and into niches where chrome films typically dominate. So far, so good, with a few intermittent bellyflops of course.
