Adam

The Adam (アダム) is a cardboard box camera sold by Sone Shunsuidō from 1918.[1] It has no viewfinder and no shutter (the exposure time is controlled by the lens cap). It does not take plate holders, and No.0 plates (4×5cm) must be inserted into the camera one by one in a darkroom.[2] The Adam was the first Japanese camera to sell for ¥1.[3]
