After reading about the rich color saturation of Velvia 50 and the pastel color rendition of Astia 100 I made some identical 4x5 architectural shots using Astia 100 and Velvia 50 in daylight. I exposed the Velvia at the rated EI 50 rather than at 40 as I have seen recommended by others. I had not used either film, but I have used Provia with consistently good results. I expected to see a drastic difference, but to my surprise there was a subtle difference. The Velvia has warmer shadows which I much prefer over the slightly bluish cast of Astia and Provia. Greens were noticeably warmer also. If I view the Astia transparency alone it looks perfectly acceptable. When the two are side by side the Velvia wins with more pleasing color in my opinion. I think if I had made a Provia shot too, probably it would fall right between the Astia and Velvia. Now I am curious as to how Velvia 50 compares with Ektachrome VS. Any comments?
