Thanks, that's some useful information. It's confusing because the various RAW 
convertors work differently, and most of them do some sort of automatic 
lightness or gamma correction even in 16-bit mode. I'm OK with starting with 
a completely uncorrected image if I really really want ultimate control. The 
confusing bit was all the discussion I've read about using input profiles in 
Digikam doesn't make it clear that these aren't really for 16-bit RAW 
conversions.
