To meet changing aesthetics, manufacturers of collodion printing-out papers began to produce papers to imitate the surface and tonal qualities of platinum prints. These matte collodion papers became the choice among portrait photographers. Toned (treated with a metallic solution in order to modify the overall color of the image) with either gold or platinum, these prints have a distinct brownish to neutral-black hue and incredible stability.
