Having seen some of this paper first hand in Vegas during Photoshop World 07 (courtesy of Vincent Versace,) and pressing my nose against it - it's the real deal! Vincent showed us this "top secret silver halide" inkjet paper during a private lesson on IR photography and printing. Alhough he couldn't reveal it's name or who made it, but it's clear that the recent EFP announcement is what we saw. If you're printing on K3 inks, you will deffinitely want to add this to your arsenal.
Scott Kelby wrote on the Photoshop Insider Blog:
The black and white reproduction on this paper is just off the charts for anything I’ve seen coming out of an inkjet, and I’m now spoiled to the point that I’m not sure I’ll be able to print on anything else. I really think the texture, look and feel of this new fiber-based paper is going to finally win over that last bastion of the photographer who was clinging on to the notion that lab prints were still king. This is that big a deal.
Also, I found this interesting; while this new Exhibition Fiber paper is now clearly THE paper for black and white, I was stunned by the quality and richness of the color reproduction as well. This paper is just sick!!! (in a really, really good way).
