Hey Austin, recently I did an RGB scan of a BW negative (the Konica IR
you've seen, with it's dense blue base) on my Leaf (max res, HDR) and the
red channel was the sharpest channel! I was shocked, as that deviates from
my experience and expectation. Any ideas as to why the sharpest channel
might vary on a scan by scan basis? Could it be calibration drift? Could
that affect the sharpness of channels?
