Gum over platinum
text:
Gum over platinum is a historical chemical photographic process, which was commonly used in art photography. It is a complex process, in which a specially treated platinum print photograph is coated with washes of gum arabic, then re-exposed to the same photographic negative. The finished process results in a sepia toned print, and is said to impart added luminosity and depth. It is sometimes called "pigment over platinum". To sensitize the gum arabic it must first be placed in contact with ammo
