Mike, maybe you don't understand this resolution thing, it is confusing.
The D5 does not produce a 39meg file, if it did they would be advertising
the fact all over the place.
Here is a quote from the Cannon site:
File size:
(1) Large/Fine: Approx. 4.6MB (4,368 x 2,912) (2) Large/Normal 2.3MB (4,368
x 2,912) (3) Medium/Fine: Approx. 2.7MB (3,168 x 2,112) (4) Medium/Normal:
Approx. 1.4MB (3,168 x 2,112) (5) Small/Fine: Approx. 2.0MB (2,496 x 1,664)
(6) Small/Normal: Approx. 1.0MB (2,496 x 1,664) (7) RAW: Approx. 12.9MB
(4,368 x 2,912)

If it could produce a 39meg file they would certainly say so.

I didn't see Polidori's photos but if they all look a little blue to you
that may be a sign that you monitor is not color corrected. Since you seem
to be a computer buff I guess you know that monitors do not always display
the correct colors and for critical work they need to be calibrated so
things have the correct color. I have been doing this stuff for a few
years and it is true if a scene is illuminated just by sky light only such
as in the shade, can have a bit of a blue cast. But if you have a blue sky
that means you have the sun out and scenes in sunlight never have this blue
cast - the engineers at Kodak have figured this out and make their film to
show pretty damn good colors.

Better get your monitor calibrated if you want to peruse a career as photo
critic.
Aloha
