A bit more information from my limited testing:
The canned profiles were not bad. The colours I get are better than the canned Harman FB Al profile I tried on that paper: specifically in the greens.
Gloss differential is higher than Harman FB Al or Epson Exhibition Fiber.
The surface texture, to me, is nicer than Exhibition fiber . . . more regular and not as obvious with more stippling than Harman.
The paper base colour is a tad warmer than Harman FB Al., but not as warm as the Harman FB Al warmtone.
Thanks for the info!
I was at the ImagingUSA convention in Nashville a few weeks ago and stumbled onto the Canson booth and they had some hung prints of the new Baryta paper taken by the very talented Rojelio Reyes Rodriguez, who I believe was there discussing his work, and the images (and the paper itself) were most impressive. I've got some on order myself from B&H but have no idea when I'll actually get it. I'll be curious to compare it to my reference papers (Epson Exhibition Fiber and Hahnemuhle Fine Art Baryta - I'm not as big a fan of the Ilford GFS as others are (I find it a bit lacking in depth/sense of dimension and also in the blacks compared to the EF and FAB) and I don't like the Harman stuff at all) and see how it goes. Of course paper choice is hugely subjective so one mans poison might be another mans heaven. But man, those prints I saw hanging were really well done and that paper in particular looked gorgeous, particularly in the sense of depth and dimension. I'll have to see how the metamerism and gloss differential aspects hold up to other papers, but I was very excited about what I saw. As an aside: the folks at the Canson booth were great; very friendly and helpful. I wish they had samples of the Baryta paper with them but unfortunately they did not. (As for the show itself; the most impressive thing I saw were prints in the Epson booth from the 9900, taken by Douglas Dubler, that were about as flawless as I've ever seen; most impressive stuff)
If anyone else tries this paper and has similar tastes to mine, chime in, papers are, again, so subjective, that it's important to get as many opinions as possible across a wide range of users.
