A carbon print is a photographic print produced by soaking a carbon tissue in a dilute sensitizing solution of potassium dichromate. The solution also consists of carbon, gelatin, and a coloring agent. The process was created as a result of print fading in early photographic processes, and was patented in 1864 by Joseph Wilson Swan.
