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.
