OK, please indulge me with one more illustration: As we know, so much of the noise differences between cameras has to do with the NR algorithm. On the following pictures, I took the RAW files from the previous test, and opened them in Adobe Photoshop Elements 6.
Here is a 100% crop of the ISO 100 shot:
Here is a 100% crop of the ISO 3200 with no NR:
Here is a 100% crop of the ISO 3200 with K-7 in camera NR on HIGH:
And here is a 100% crop of the ISO 3200 shot with Adobe Photoshop Elements (the cheap one) luminance and chroma noise reduction:
Interesting huh? I actually see more detail in the APS NR than the K-7 High NR, even though the APS NR shot is a lot less noisy.
