I started using FB Matte surface paper. Initially, I used them because I was going to hand-color but I'm starting to like this texture for regular prints.
Even when images are tack sharp, I see some gentle-ness that I can't get from glossy. Also, even the deep black seems not so deep - no that I see contrast much lower but it's gentle... in a way it's hard to describe.
Behind glass and framed, the surface texture itself is kind of hard to tell but this mellowing of images do remain.
Seem to echo my sentiment in images very well.
