I used Hahnemuhle for years, but the Harman blows it away. I am trying the new Warmtone, but frankly when it runs out I'll go back to the regular gloss (for 8 1/2 x 11 only).
Which Hahnemuhle? The Fine Art Baryta is a new paper?
I have the Harman regular and warntone. Both are nice, but I have always preferred a cooler paper. No to the Agfa, yes to the Ilford Galerie back in my darkroom days - guess that was 1982?
I tested 35+ papers last winter. Then I bought stocks of 6-7 for further testing. The Harman, Hahnemuhle, and Epson were 3 that I chose for more testing.
The only matte that I still have is the Moab Entrada Bright White. Only because I have punched and scored portfolio pages from Moab (actually Lost Luggage.) I still need to decide how to handle my portfolios.
We should also distinguish between B&W and Color. For color I use the Epson Exhibition Fiber, Hahnemuhle Fine Art Baryta, and Harman Glossy Fiber AI as my premium papers (really the Hahnemuhle though once the othwers are gone.)
I use Epson Premium Semi-Matte, Premium Luster, and Premium Semi-Gloss for proofing and everyday prints.
For B&W I also use the Innova
Glossy Warmtone and the Harman Warmtone as well as the above papers. Goes well with the B&W inks I have with no toner. The cool inks go too blue for me with magenta and cyan added. I prefer no toner at all.
Plus the Entrada Bright White for portfolios, B&W and color, as mentioned.
