Sanger Shepherd and Company Limited was an electrical goods and photographic company that developed the Sanger Shepherd process for taking colour photographs.[1] [2] The company led by Edward Sanger Shepherd was active from 1900 until 1927.[3]
Sarah Angelina Acland of Oxford, England, used the process among others for her early colour photography at the beginning of the 20th century,[4] with examples held at the Museum of the History of Science, Oxford. The process involved taking separate photographs through red, green, and blue coloured filters and then combining them later. A complete outfit cost £9/6/6 (£9.321/2p).
The dye inhibition method of colour photography which underpinned the Sanger-Shepherd process set a pathway for future processes, notably Kodak's Dye-Transfer process of 1946.
