A one-shot colour camera is an early, now largely obsolete, plate camera designed to create three separate colour separation negatives-typically red, green, and blue-from a single exposure. This allowed photographers to capture all the necessary colour information at once, rather than using multiple exposures.
These cameras were important in the development of colour photography and early colour printing processes, enabling more accurate colour reproduction. While modern digital cameras have replaced this technology, understanding one-shot colour cameras provides insight into the history and evolution of colour imaging techniques.
