Excellent reply unfocused!! It would be hard to believe u r not a woman LOL!
Truth be told, as far as skin tone (out of in-camera jpg) is concerned,
I have not seen a Nikon to be able to match my old 5D2
When my friend with a D800E shoots models side by side with me, the models have
always preferred the 5D2 jpg on the back of the camera!
I think Canon definitely has a successful secret formula on in-camera jpg rendering.
To me, it is even more obvious in high ISO skin tone rendering.
However, I must admit that with proper RAW processing & skill, Nikon's skin tone can match
Canon but that is a lot of extra work. I would rather get it right in camera.
