If you want no grain, shoot Astia (RMS 7, finest grain slide film).
Grain-wise Velvia 50 and Velvia 100F are nearly indistinguishable as
far as I can tell (RMS 8 vs 9). Note that Velvia 100 (not F) is also
RMS 8.
But I like grain. Which is why I shoot Tri-X pushed to 1600+.
I shoot a lot of Delta 3200, so I see you there.
I'm not suggesting that I am looking for the finest grain. When did
Velvia 100 non-F launch? I was running my lab until May and at that
point we had heard nothing about it -- was it late summer? I have to
wonder what the point is of such a film -- they didn't keep dual
inventory of Provia 100 F and non-F nor Astia 100 F and non-F.
My own tests comparing Velvia 100F to old Velvia 50 didn't yield a
significant difference in contrast or saturation, though they were
checker-chart and skin tone tests under sunlight and strobe rather than
real-world images (mostly done to check comparative processing times --
E-6 is pretty flaky as a standard these days, with every manufacturer's
own E-6 equivalent seemingly designed to make the other guy's film look
bad -- and I'm going from memory, but I think I ran the 100F a little
longer in the colour developer than the 50). Is there perhaps an
online comparison that someone has done?
