While testing my input profiles as suggested in "Real World Color
Management" it seems that I have the same problem with ColorLab version 2.8
on mac OS X and OS 9.2. If I convert a target text file to tiff format and
open it in Photoshop the colors are completely changed (e.g. LAB (50,0,0) to
(50 -128 -128)). It looks like a number problem: L is ok but (a,b) are 128
too low. Or am I doing something wrong in ColorLab? And if I create a tiff
measurement file in Photoshop and open it later in ColorLab the same effect
appears vice versa (only with mac OS X). Any idea?

PS: Real World Color Management is an excellent book. Many thanks and
congratulation to Bruce, Chris, and Fred.
