The new pro E100 emulsion loses about 2/3 of a stop in long (> 1 minute)
exposures. Additionally, the color balance does not appear to shift. This
is not to be confused with the amateur film Elite II, which has very poor
reciprocity behaviour compounded with signigicant color shift.
I can't speak to the Velvia.
