FC (photo camera) is a family of Soviet large-format direct-sight cameras, similar to pre-war German Görlitzer cameras. Large-format cameras of the "FK" family were produced in several versions, for different frame formats, with slightly different names: FK 13x18, FKD 13x18, FK 18x24, FKD 18x24, FKP 18x24, FKR 30x40. These cameras are known to several generations of Soviet people; they have been produced since 1930 and were used in almost all photo studios of the Soviet Union. The cameras have a wooden folding body and a focusing bellows made of fabric or thin leather. The design of the entire FC family is similar to most road cameras: unlike other types of large-format equipment, in which the lower base folds forward when unfolded, in FC cameras the rear part of the horizontal board is folded.
Focusing is also carried out by moving not the objective board, but the cassette part mounted on a rack and pinion mechanism. The "double stretch" bellows of the FKR cameras allowed macro photography on a 1:1 scale. The design of the body allowed for movement : lens displacement and cassette tilts in two planes. When storing and transporting, the device is disassembled and placed in a suitcase with accessories.
The cameras were supplied with a durable wooden tripod with extendable supports, the cameras were mounted on a dovetail mount and secured with a 3/8- inch screw.
