Hi
Brian,
Velvia
does not have good reciprocity characteristics. It fails quickly,
requiring 1 full stop of additional exposure at 5 seconds. The color
shifts warmer and then goes green. It would not be a good choice for astro
work or night-time landscapes, etc.
E100VS, on the other hand, should work well. I have used E100S
as my nighttime landscape film for a few years now, and it has performed
beautifully. I love the VS film for daylight shooting - I just have not
had a chance to use it much at night. Since it is in the same film family,
I would suspect it should perform similarly to the E100S.
I have
some recent examples (Feb. 2002) of night shots (volcanoes, in this case)
done on E100S on my website:
All
the night shots were between 5 minutes and 30 minutes at f/4 on E100S. Two
friends/colleagues who were with me insisted on using their beloved Velvia and
got NO usable nighttime images.
That
said, Velvia is a wonderful, extremely fine-grained film (90 lpm) for daylight
shooting, particularly in overcast conditions (it is one of, if not
THE highest contrast slide film). E100VS has a little less contrast,
but not much less, and is also fine-grained (85 lpm). On those bright,
sunny, sidelit days, you might want to give Provia 100F a try
too.
Take
care,
