Rafe,
I looked at your scans in PS, and they are impressive, but one thing I saw
raises a somewhat generic question for me.
The blue channel of the pad lock image shows what appears to be jpeg
artifacts, but none of the other channels do. I know the blue channel is
typically the noisiest channel of a scan, but I forget why. Isn't it because
the CCD elements are least sensitive to blue light? If so that is a hardware
thing. But jpeg is a software thing, so why would it also show up
predominantly in the blue channel? Is that typical of jpegs, or was it just
a fluke or coincidence here?
