The Imperial is a range of folding field cameras made by Thornton-Pickard in the early years of the twentieth century. The cameras are made from mahogany with brass fittings. Double- and triple- extension models of the camera were available, as was a camera with a built-in focal-plane shutter. Notes on the cameras at Early Photography describe the Imperial as 'mid-range'.

Unsurprisingly, for a company which made a speciality of roller shutters, a special model of the camera was made with a built-in shutter at the rear. It was made in the half-plate size (Early Photography states that a full-plate version was made later) and with triple-extension bellows.
