Blue sky Noise Tests: Pentax K20D & Nikon D300

Noise tests from 200 to 6400 ISO. Please note that Pentax and Nikon expose scenes very differently, with Pentax producing much darker images at a given judged exposure.
Because of this, a Pentax image (for e.g.) at f8 and 1/640th of a second will be darker than the Nikon image.
Images where bracketed by 0.3 stops over 5 images each. Raw files where then processed in PS CS3,
no noise reduction was used but images were sharpened 57% each so as to simulate a normal
finished process. The images sections here are unreduced in size.
