My discussion of
films is generally in an order from least color saturated
to most color saturated. Fuji Velvia 100F is a film that was
introduced as an "improvement" over the standard Fuji Velvia 50 featuring 1 stop faster ASA rating and fine
grain. They tell us that the grain is fine, but I will never
be able to tell the difference in grain size between any Fuji
film rated at 100 ASA or slower.
The big difference
between Fuji Velvia 100F and 50 is that 100F has slightly
toned down color, especially in the red region. You can use
it to photograph skin, but the results do come out looking
redder than what the eye sees.
Compared to Provia,
Velvia 100F has brighter colors and is warmer - that is to
say it is the opposite of Provia's blue color shift.
I would consider
Velvia 100F to be a great overall film and would choose it
over Velvia 50 if I know I may need to take pictures with
people in them. The brighter colors and warmer feel makes
it a better choice for general photography for myself compared
to Provia.
