I was again impressed with the noise levels of the 20D at ISO1600.
HERE is a 50% crop
of picture #4 in my other thread to show how little noise is present at ISO1600. This is converted with Photoshop CS with sharpening, luminence, and colour reduction of 10,10,15 respectively. No noise reduction at all.
This would be a good representation of how clean a 8x10" print would look.
