[2] The earliest references to Walton Adams's involvement in photography show him to be working in the Southampton studio of Samuel J. Wiseman (1825-1872) as an apprentice in 1861.
[4] Photography historian S. K. May on the Southampton Victorian Photographers website speculates that Adams possibly worked with Richard Leach Maddox, the inventor of lightweight gelatin dry plates.
[9] An unpublished autobiographical account mentions that he photographed "about sixty thousand sitters" during his career and he singles out those whom he considered to be the most illustrious: Queen Victoria and General Charles George Gordon.
[10] Thirteen Images attributed to Adams appear in photographic collections of the National Portrait Gallery,[9] Examples of the work undertaken by his son Marcus and grandson Gilbert Adams also appear in the National Portrait Gallery's collections, underscoring Walton's influence.
Walton's work can also be seen in the photographic collection held at the Conway Library, Courtauld Institute of Art.
