All fine art photographs are printed by a professional lab on premium acid-free, archival quality paper. Select prints have a choice of two finishes - matte or metallic.Matte (luster) – This paper provides accurate color and realistic saturation and works well for all images. Its matte finish resists fingerprints and reduces glare considerably compared with glossy paper.Metallic (glossy) – This stunning paper features a pearlescent surface and has a rich, distinctive metallic look. It uses a patented combination of film and laminate layers resulting in a striking metallic shine. This paper is best suited for use on photographs with mid to dark tones. Lighter tones do not reproduce as well on this paper.
