The RMS granularity index for velvia is 9; E100VS is 11; Provia 100F
is the new standard for slides at 8.
As far as contrast is concerned, Velvia has a low contrast index (@
1.6:1 contrast ratio) of 80 lines/mm and a high contrast index (@
1000:1) of 160 lines/mm. Provia 100F, like Provia 100, has a low
index of 60 and a high of 140. The low/high figures for Fuji Astia
are 55/135. These numbers are taken from fujifilm.com and kodak.com .
Kodak.com does NOT list corresponding data for E100VS as yet.
