I generally look at his radiation count web page (OK, so I am a bit of a geek), but I saw that Ken R. has today posted a set of photos he took with his Leica M9 on a tour of central CA.
I have been reviewing some of my recent brightly lit shots and cannot for the life of me (even with the Nikon vivid color settings) see how to get such tack sharp shots with those very over-cooked colors he gets without loss of IQ.
Increasing the sharpness and color saturation in whatever software I use (Capture NX2 Or View NX2 - hey.. this *IS* in the Nikon software part of the forum), to the extent that I end up with the eye-melting amount of color he has, results in some loss of definition/distortion in my images, compared to how they usually are...
Assuming he only uses the Leica software and shoots in raw, compared to the much more realistic Nikon results, the Leica raw to JPG software can't be all that far out, can it?
