Two other papers to consider, both by Hahnemuehle:
Fine Art Pearl - A very nice, substantial fiber (read: non-rag) based paper with a lovely, very subtle smooth pearl finish. The pearl finish is much more subtle than the Ilford Smooth Pearl, IMHO. The FAP also does not have the platicky/RC feel of the Ilford. The DMAX on this paper is outstanding and the color rendition is excellent. It is fairly bright white (105, if I recall correctly) - quite a bit more so than the H's Photo Rag Pearl, which has a slightly warm tone to it - but, unlike the Photo Rag Pearl, has optical whiteners which can potentially reduce its archival quality. (The assumption so far, among most, is that the whiteners being used by H in its fine art papers are in the paper, rather than the coating and are sufficiently well buffered that diminished brightness and/or yellowing should be minimal over time and should not effect overall print life substantially. But, only time or the Wilhelm Institute will tell.)
Another paper that I have just tried and absolutely love is H's Photo Rag Satin. This is an all rag paper, but does have some whiteners in it. The cool thing about the paper is it appears matte when unprinted, but after printing the printed areas carry of lovely, very subtle satin sheen to them, while the unprinted areas remain matte. This effect, with the right picture, is absolutely stunning! I printed a shot I took of some sea dunes with sea oats growing in them and a fairly dramatic sky behind them and the impact imparted by the print on this paper was far, far greater than a print of the same shot using the Ilford Smooth Pearl. It was night and day.
You can get a sampler pack of 2 sheets each of 9 different Hahnemuehle papers, including both the Fine Art Peal and the Photo Rag Satin (but unfortunately not the Photo Rag Pearl) from Adorama (or other online shops) for about $18. Definitely a nice investment if you want to check out some of H's excellent papers without springing for a whole box.
