Files that I've matched from my raw scanner RGB
to the Generic Lab Profile open in Photoshop
with the image mirrored.
If I match to Adobe Photoshop CIELAB (file named "pslabpcs.pf")
this does not happen.
I do not understand why.
I am also still baffled by:
a) Discovering that there are multiple Lab profiles.
This was a rude reality check on my plans to archive our files
in device-independent, "known" space.
b) Adobe's TWO profiles, which both show up as
"Adobe Photoshop CIELAB", in ColorSync pick lists,
though one has a file name of "pslabpcs.pf",
and the other has a file name of "pslabint.pf"
I doubt that these questions are questions to most of you,
but they make me wonder what else is going to spring
out of the bushes at me as I venture into
this tangled land of computer-based color control.
I need a machete.
