Digital BW, The Print

This is a Photoshop script, that works just fine for those of us who don't have anything more than a scanner.

You print out a 50ish step chart, scan it, run the script, save the curve, and it works like a charm, as a saved curve you apply before saving your file before printing...it works with QTR or with the Epson driver.

This was made typically for creating digital neg's, but I found it works perfectly for creating curve for b/w Epson printing.

(I have no involvement w/this person who created this...am just sharing what I am using on all 6 of my Epson printers....it works great...I love simple solutions!)
