Paul,

Nice, huh? <G> I think this may overcome one of the inherent problems with
RGB separation curve workflows. In 8-bit the curves really stressed the
image data and if the data was already on the edge you could wind up with
problems in the final print. Staying in 16-bit you have a much, much larger
margin for error.
