Digital BW, The Print

Hi Clayton,

Calculator is here
http://www.brucelindbloom.com/index.html?CompandCalculator.html

<http://www.brucelindbloom.com/index.html?CompandCalculator.html>Its funny
because I just don't get dmax, it increases as the image get darker !!
what's that all about.
I know where it comes from and hence why old timers :) use it, but L* is so
much more useful and spectros/software don't output dmax directly to my
knowledge. When you use your spectro how you get from L* to dmax? Or are you
using a reflective densitometer :)

Mike
