AFAIK museums and art galleries gave up trying to nail down a definition of a photograph. To photographic images they append the captions "Type C print", "Dye Transfer print", "Gelatin Silver Print" (or "Silver Bromide print"), "Bromoil print", "Palladium print", "Platinum print", "Screen print", and on and on ad nauseum. Even Ilfochrome (formerly Cibachrome) prints get a description along the lines of "Azo Colour print" or something to that effect.
IOW they are all "prints". regards, Anthony Farr
