Re: Linearizing a QTR Curve

2005-02-21 by Louis Dina

Hi Roy.

I suspected QTR could accept RGB data for linearization, but wasn't 
sure.  I didn't even think about 16 bit.  Thanks for the 
clarification.

BTW, I love both your proofing techniques - ie, Gray Lab profiles, 
and creating soft proofing profiles with a 21 step wedge.  Great 
contributions that work very well.  Thanks again.

Lou
