Wow, definitely a welcome addition to the DN arena. I for one have used Pictorico White-Film (whatever the code is) to print portraits from DN's with impressive results. Portraits tend to be very unforgiving.
I picked up a batch of white film made by Inkpress. I've yet to try it but will certainly post results for others to read. Personally, I think both Pictorico & Inkpress are highly overpriced. This new brand from Freestyle, though slightly less expensive, is still exaggerated, and IMHO, priced as such only to make its entry into the DN media arena.
