disk film

Disk film was a type of photographic film used in some compact cameras, notable for its circular shape and light-tight cartridges. Each disk was 65 millimeters in diameter and coated on a polyester base. Within the camera, the disk would rotate, allowing up to 15 exposures, each measuring 8 x 10 millimeters, to be recorded around its circumference.1

This design offered advantages over traditional rolled film, as the disk lay flatter in the camera, making it suitable for more automated photofinishing processes. However, the high printing magnification required for these small frames limited the overall image quality. The Kodak camera, introduced in 1888, was a pioneering device that made photography accessible to amateurs, initially using paper negatives before transitioning to film on a plastic base.12
