Glycin (N-Para-Hydroxyphenyl) is an excelent developing agent for both film and paper. It is fine grain, ultra clean working, lengthens the life of phenidone, and produces attractive warm tone prints with the subtlest highlights.

Until the advent of 35mm film, with the resulting emphasis on fine-grain developers, glycin was used mainly in paper developers. Now it is sometimes used in combination with other developing agents for fine-grain film development.

Print craftsmen and women long ago recognized the Ansco 130 formula based on glycin as the experts choice. Ansel Adams used a modified version of it for some of his very finest work.
