Three Friends, about 1860
© Science & Society
A collodion positive (ambrotype) of three serious- looking men, all seated and wearing hats, taken by an unknown photographer in about 1860. These smartly-dressed friends are pictured in front of a painted background of a grand fireplace. They are all in suits and have flowers in their buttonholes, perhaps indicating this was taken on a special occasion. The collodion positive process (also commonly known as ambrotype) was popular during the 1850s and 1860s. An underexposed collodion negative on glass was backed with a black opaque coating to create a unique positive image.
