The Shackman Four x One is a passport camera for the 8.5×10.8cm instant film packs of Fuji and Polaroid. The camera allows 4 exposures on each sheet of a film pack. Its dark chamber is divided into four separate sub-chambers, each with a rectangular image frame upon the film plane. The lens/shutter-unit can be positioned over one of these sub-chambers. Shutter speeds are selectable between 1 sec. and 1/500 sec., and possible apertures are between f11 and f64. The camera has two accessory shoes and two flash cable connectors. It was made by the British camera maker D. Shackman & Sons.
