Next to the pinhole model, a box camera is the simplest form of camera available.
It is called a box camera because it's basically just shaped like a box. Box cameras
have very simple optical systems. They often just use simple meniscus lenses. They usually have a manual focusing system only, along with manual controls of the aperture and shutter speeds. Because of this, box cameras are designed and suitable only for daylight photography. Photographic flashes were introduced to box cameras during the 1950s which made them usable for taking indoor photos. They were quite a fad item back in the 1950s, but as technology changes so do the fads. The first box camera was introduced in 1988. Newer versions of box cameras include the Kodak Instamatic Camera and modern day disposable cameras, which can be bought for less than $10.
