Take a look at this beautiful photo of Zurich, Switzerland. This photo shows the city back in 1860. This image is what’s known as an albumen print, a technique invented just ten years prior to this photograph. It uses albumen found in egg whites to bind the photographic chemicals to the paper, and was the primary form of photograph printing until the turn of the 20th century.

Also, we posted a great one of Geneva the other day. Don’t miss that one.
