Sepia is a red-brown ink derived from the species Sepia officinalis, a cuttlefish. It was very popular with artists in the nineteenth century…
The sepia tone employed in black and white photography is the result of converting the metallic silver in a photograph to a sulphide.
It not only made the photo more attractive and fashionable, but it also elongated the image's permanence. Today, sepia toning is a term for any monochromatic photo with a brownish tint to make it look old fashioned.
Although true sepia toning renders an overall brownish tint to a black and white photo, we can make it more interesting by combining the silver gray of the high and middle tones of a black and white photograph with the rich warm darks of a sepia toned image.
