[alt-photo] Re: Epson 3880 and Snow Leopard

[Alan MacKellar]

As someone who is totally ignorant, I need to ask two questions.  I
purchased a UV unit made by Photographic Formulary, which is a tube box.
What is a NUARC?  What is a Snow Leopard?  I am fully committed to using a
PC.  Does all of this mean that I am doomed on PDN, which has given me grief
with my basic calibrations for Pt/Pd = 1/3, COT320 paper, and the magic
brush.  Must I stay with QTR?

Kees,

Thank you so much for that explanation. That clears up the confusion I  
was having and helps with digital negatives which I am starting to  
print.

Sincerely,
Doug
