A collodion positive (ambrotype) of the Reverend Errington and his curates, taken by an unknown photographer in about 1854. The Reverend W Errington was Rector of Ashbourne, Derbyshire. Photographed with him are W A Duckworth (1829-1917), E Worthington (seated) and Lance Errington (seated), presumably a relative. 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.
