OT - Inkjet negs, change of media.

[Paul Viapiano <viapiano@pacbell.net>]

Hi all...

I'm not a digi-neg guy, but am very interested for the future.

So FYI...

Last night, I tried printing a neg from Photoshop onto a fixed out piece of 
APHS ortho film, just for the heck of it. It didn't really take to the film, 
I could see an image alright, but the ink was pooled though almost dry. Just 
for grins, I put the neg into a tray of warm water overnight, and this 
morning all that was left was a faint green image of the neg.

This was dye, not pigment, ink...but I guess that green dye is pretty 
tenacious.

Paul
