There is a much simpler way to fix incorrect Lab tif's exported from
ColorLab: a Photoshop Lab curve which does the following to the a* and b*
channels:
1) add 128 to input values between -128 and -1
2) subtract 128 from input values between 0 and 127
I have sent such a curve (Photoshop .amp file) to Chris and Bruce for
testing and hopefully they will post.
