Hand-colouring

Hand-colouring refers to any of a number of methods of manually adding colour to a black-and-white photograph or other image to heighten its realism. Typically, water-colours, oils and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes. Some photographic genres, particularly landscapes and portraits, have been more often hand-coloured than others, and hand-coloured photographs have been popular enough that some firms specialised in producing them.
