Re: [Digital BW] LAB Step Wedge

2004-12-07 by Steve Kale

Because it converts the profile but the underlying pixel values don't change
- you still have L=54 at the 50% step for example (rather than L=50) - or am
I doing something wrong?  By a LAB step wedge I mean one where L steps down
from 100 to 0.
