And does inflate my view of digital photography as being much more wide range than all the BS a while back when they were selling the Fuji S and saying it gave you what color neg gave you claiming a normal Nikon or Canon body gave you what a slide would. Baloney in my book. I'd try to show us what you are doing visually Do a screen dump or something. It all comes down in the end to you aim your camera at a black cat and what bias do you set it out to have it come out right. Minus 2 or 2.5 or 3 or what? But the fact that were starting out with a normal bias of almost minus 1 to start out with skews things and makes it hard to conceptualize. I tend to be set at a default for most things a minus .7 Many of us from what I've seen seem to be not far from that.
