Hand-colouring or hand-coloring refers to any method of manually adding colour to a monochrome photograph , generally either to heighten the realism of the image or for artistic purposes. Typically, watercolours , oils , crayons or pastels , and other paints or dyes are applied to the image surface using brushes , fingers, cotton swabs or airbrushes. Hand-coloured photographs were most popular in the mid- to lateth century before the invention of colour photography and some firms specialised in producing hand-coloured photographs. Monochrome black and white photography was first exemplified by the daguerreotype in and later improved by other methods including: calotype , ambrotype , tintype , albumen print and gelatin silver print. The majority of photography remained monochrome until the midth century, although experiments were producing colour photography as early as and some photographic processes produced images with an inherent overall colour like the blue of cyanotypes. In an attempt to create more realistic images, photographers and artists would hand-colour monochrome photographs. The first hand-coloured daguerreotypes are attributed to Swiss painter and printmaker Johann Baptist Isenring , who used a mixture of gum arabic and pigments to colour daguerreotypes soon after their invention in Later, hand-colouring was used with successive photographic innovations, from albumen and gelatin silver prints to lantern slides  and transparency photography. Parallel efforts to produce coloured photographic images affected the popularity of hand-colouring. In Daniel Davis Jr. The results of the work of Davis and Thompson were only partially successful in creating colour photographs and the electroplating method was soon abandoned. In Levi L. Hill announced his invention of a process of daguerreotyping in natural colours in his Treatise on Daguerreotype. Hill delayed publication of the details of his process for several years, however, and his claims soon came to be considered fraudulent. When he finally did publish his treatise in , the process — whether bona fide or not — was certainly impractical and dangerous.
