A collodion positive (ambrotype) of a boy holding a fishing rod with his arm around his younger sister, taken by an unknown photographer in about 1860. This photograph has been hand-coloured. Both children look rather bored, presumably from having to remain still whilst the photograph was exposed. The little girl's head has moved during exposure, as her features are blurred. 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.
