By the 1950s, the availability of colour film all but stopped the production of hand-coloured photographs. The upsurge in popularity of antiques and collectibles in the 1960s, however, increased interest in hand-coloured photographs. Since about 1970 there has been something of a revival of hand-colouring, as seen in the work of such artist-photographers as Robin Renee Hix, Micheal Paul Cole, Elizabeth Lennard, Jan Saudek, Kathy Vargas, and Rita Dibert. Robert Rauschenberg's and others' use of combined photographic and painting media in their art represents a precursor to this revival.
