Gamma Photographic Labs

Description

The visual and emotional impact of black & white photography is greatly increased with the addition of color. We specialize in hand coloring and chemical toning with selenium, sepia, gold, red, blue, copper, polysulfide and thiocarbamide. Toning can add to the archival life of a print. The grains of silver in a gelatin silver print bond easily with elements in the atmosphere. The brownish spots sometimes seen on older black and white prints show the reaction of silver with hydrogen sulfide to form silver sulfide. This reaction, when controlled, is the same process we call sepia toning.
