Hahnemuhle's Photo Silk Baryta is suppose to be the best Baryta paper in the world if archiveability is not your priority, according to this review.http://blog.brettlerickson.com/2016/04/25/review-hahnemuhles-new-photo-silk-baryta/
From the horse's mouth:- FineArt Baryta 325 as an alternative for Gloss Art Fibre 300
If Harman by Hahnemuhle Gloss Baryta is the same paper as Hahnemuhle Photo Gloss Baryta, why is one twice the price? Is one better than the other?
