By the way, a 12Mp D3, can't possibly compete with a 12Mp D300S when cropping to the same magnification.
PPD, pixels per duck! Think about it... Simple maths. Brick size pixels.
That's not true Robert, despite your maths.
I struggled over far too many experiments with the D3 and the D300 (notS) trying to decide if there was any difference in image quality cropping a D3 to D300 frame. Inconclusive at best. The only image benefits come from not emphasising noise by cropping. So in poor light the D3's better handing of noise ( 1-2stops ) meant cropping never emphasised the noise as much as the DX performance at the same ISO.
In good light there was no difference.
I am not ignoring this post Eric, I appreciate the challenge, I simply want to gain a better understanding before I respond.
I do still feel Jeff's question is about more than noise, it's about improving his images, if that's possible! Noise isn't the only issue, at least, not in my opinion. I tried to simplify it.
Obviously it needs backing up with something demonstrable. I have both the D300S and the D3, so I will try to compare the two.
