Gelatin-Silver prints have a deep, bright range of grays and deep, dark blue-blacks. The surface can be matt or glossy. Silver mirroring is characteristic of late 19th and early 20th century prints. Chemical residue from the developing process generally causes fading, loss of detail in the highlights, and in some cases yellow/browning of the print. Sepia toned prints from the early 1900s display less mirroring.
