I've posted in my photo.net folders a group of photographs I shot with Ektar 100 this morning. These are all scanned on Nikon Coolscan IV ED, with Nikon Scan 3.1. I work in sRGB color space, so there's some gamut clipping here. As for film grain, there pretty much isn't any! I can't resolve any grain in the sky with the Coolscan IV. 2900 dpi just isn't enough to catch the grain on this film. There's some noise in underexposed areas, but even it is quite muted, and very fine. Nothing that you could call "speckled". It doesn't like underexposure. It doesn't go grainy, it just goes dark, with a thump. I had more underexposed shadows than I would have liked, given the high vignetting of the CV 15/4.5 lens I used for many of the photos. (It may also have a T-stop versus f-stop issue, and the Canon 7s doesn't meter through-the-lens.) Like Ektachrome E100G, it will gleefully go cold blue when you take pictures lit only by sky. Also, shadows just tend to go a bit blue. This corresponds with the HD curves in the Kodak data sheet, the blue is a bit out of parallel in the shadows. As for the colors, they are perky, but I think it's in good taste. I think greens get the biggest jump, along with red and orange. Yellow just sits there, doesn't have as much fire as the other colors. I'd say it's more saturated than E100G and E100GX. I've never used E100VS, so I can't compare it to that. It's certainly not as warped as my stereotyped impression of Velvia 50, the saturation is pretty balanced all around.
