Re: Digital Negatives on 3800

2007-08-09 by remkopieter

Hi Andy,

I made the corrections with a curve in PS. depending of the print 
results on the Kentmere paper I will use QTR or not. I don't think 
there is much to gain using QTR against the Epson AWB-driver because 
of the process to come to the defenitive print that followes.
