This box-form camera, made by Johnson and Harrison, was one of the first to be designed to take panoramic photographs on glas plates. The images it produced were of a 110 degree view on 7.5 x 12 inch (19cm x 30.5cm) flat collodion plates. As the clockwork motor rotated the camera, the glas plate was moved past a slot in the camera back, to make the exposure. Front view, with door open.
