Something to share again: On the usage of different Film Simulation in X-E1, hope this is helpful as bro pit14 had opened up my mind on this fabulous way of utilising Fuji's film settings.
"Velvia possesses a super saturated slightly contrasty look that became the darling of nature shooters. Provia was the “go-to” film for product, commercial and general use, while Astia and its lower contrast smoothness hinting with a touch of warmness was perfect for portrait and fashion work.
The X Pro 1 & X-E1 offers you a choice of Provia (standard), Velvia (punchy & saturated), Astia (soft), Pro Neg Hi (contrasty), Pro Neg Standard (great range of tones), Monochrome (b&w), Monochrome Y (Yellow filter for contrast), Monochrome R (Red filter for higher contrast, great for clouds), Monochrome G (green filter for smooth skin tones), and Sepia tone (warm old feel)."
Cheers.
