The latest photo books I received from Panstoria included samples with glossy and matte covers. The Matte covers look nice and the matte finish certainly cuts down on glare. Unfortunately black turns into a dark gray, reducing the impact of black and white or night photos. Consequently, I recommend glossy covers as the default. Matte works well but only if the photos on the cover do not contain black or other dark colors.
