A photograph of a little girl with a hoop and stick, taken by an unknown photographer in about 1860. This collodion positive photograph has been extensively hand-coloured with an oil-based paint, highlighting the little girl's cheeks, tartan dress and hoop. An outdoor scene is suggested by the landscape backdrop. 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.
