Cirkut

No. 8 Cirkut
Maker	Eastman Kodak
Type	Panoramic

The Cirkut is a rotating panoramic camera, of the type known as "full rotation". It was patented by William J. Johnston in 1904, and was manufactured by Rochester Panoramic Camera Company starting in 1905; the company was acquired by Eastman Kodak the same year. Manufacture continued through 1949.

There were several models: No. 5, No. 6, No. 8, No. 10, and No. 16, named according to the maximum width of the film accepted, in inches. The length of film (corresponding to the width of the panorama), varied by model also, ranging up to 20 feet (6.1 m) for the No. 16, yielding a single negative with an area of more than 26 square feet (2.4 m²). Thus, the information content of Cirkut images can be in the gigapixel range.^[1][2][3]
