A collodion positive (ambrotype) believed to be of a Mrs Adams (1819-1893), taken by an unknown photographer in about 1860. She is wearing a beaded necklace and two large matching bracelets, which may have been made of jet, popular with Victorians as mourning jewellery. The photograph has been hand-coloured to add a rosy tint to her cheeks and to emphasise her blue eyes. 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.
