Not a myth. I´ve been there. I am getting paid for it and I know how the crap looks i get from photographers to work with.
Yes, the D700 was a step forward in low light, anywhere else its the bad old yellowish Nikon digital look, sucky skin tones that break apart to yellows and reds once you start adjusting levels.
With film even a wrong balance looks cool, with digital wrong is just wrong and "right" is hard to hit, especially when you have to deal with a series of shots taken at different locations.
You dont have to agree (some people are just not as sensitive to color and overall balance) but please dont post something uneducated and silly as "myth".
