i'm hoping to tap into your collective wisdom before i set out on unknown
waters... i have multiple figures for a book, all the art has been created in
photoshop. they were created in RGB, and need to be converted to CMYK. here's
my question:

i heard a tip at macworld expo that you can sharpen images quite nicely by
converting them to Lab and applying an unsharp mask filter to the L channel.
if i do this, then convert to CMYK, am i going to get wild and weird color
shifts that i won't like? in effect, i'll be going from RGB to Lab to CMYK.

of course, i'm going to do some tests first, but i'm hoping someone out there
has some experience with this (or at least a good joke to alleviate some of
the tension...).
