Photographers' Formulary 06-0170 Formulary GP-1 Toner

Photographers' Formulary Gold Protective (GP) Toner is similar to Kodak GP-1 and offers maximum protection with little or no change to print color. Prints treated with Gold Protective Toner are even more stable than those toned with selenium or sulfide. This toner can also be used to protect negatives. As applied to this kit , the term “toner” is somewhat a misnomer. Almost all photographic toners are used to alter the color of a black-and-white print to enhance its emotional appeal. This is not the purpose of Gold Protective toning. Rather the purpose is protection of the silver metal in the print for archival reasons. There will be little color change of the print upon gold protective toning. However, with most prints there will be a slight shift towards a blue-black tone, a cooling, or darkening of the image.
