Trees in Sepia...
Photography was black-and-white or shades of sepia. Color photography was originally rare and expensive, and again often less than true to life.
Black-and-white as a description is also something of a misnomer, for in addition to black and white, most of these media included varying shades of gray.
Further, many prints, especially those produced earlier in the development of photography, were in sepia (mainly to provide archival stability), which gave a richer,
more subtle shading than reproductions in plain black-and-white, although less so than color.
