Moose brings up a whole bunch of points about raw conversion. If you
haven't already done so, you should mosey over to Luminous-landscape
and read the articles on the new Phase One CMOS back. The sausage
making is coming to light.
Part of what is revealed is just why so many Canon cameras "see
differently" than other cameras, and by extension, why the lowly E-1
sees differently than everything else. And also why Capture One is the
best portrait raw converter there is.
Within the wedding and portrait photographer community, the standard
configuration you seem to run across more often than not is Capture
one for raw conversion, results imported into Lightroom with a side
processing of Photoshop thrown in. Lightroom is certainly not the best
raw converter for skin tones from many cameras. Capture One is
superior, and not by a small margin.
Remember that the human eye doesn't actually directly see red. it sees
orange. Red is a derived color by by absence of green. That's right,
the human visual system determines that the color is red by
subtracting out the green. Many Canon CMOS sensors are somewhat the
same--the green detectors see up into the red spectrum. To prevent
muddying everything up, a proper raw converter won't just add/average
everything together, but must actually subtract before averaging.
This is something that just screwing around with white-balance or
curves won't fix after the conversion happens. This subtraction must
occur PRIOR to the pixel averaging stage.
As I've said so many times through the years: "Raw ain't Raw". The
Green sensels see more than JUST green. Red sensels see more than JUST
red and Blue sensels see more than JUSt blue. How we get to the point
where the "cross-talk" between the colors isn't apparent is where a
whole lot of magic happens. BTW, just in case you were wondering, the
E-1 sensels have very little overlap.
