Amanda Dunsmore’s art practice employs longitudinal research processes. Through this process she discovered the source images for The Peoples Portraits 1899-1918 (2018), at the Northern Ireland Prison Service Training College at Woburn House in Millisle, Co. Down. Dating from the 1890’s, the original glass plate negatives contain both face-on and side-profile images, taken mainly at Armagh prison by two prison officers trained as photographers, P. Egan and M. Cronin. From the thousands of original photographs, Dunsmore selected and edited 100, which date from 1899 to 1918, before the partition of Ireland in 1921.The Peoples Portraits 1899-1918, 2018.
