Diana was the name of a plastic camera produced in the 1960's. The camera was designed as an inexpensive film camera but was often prone to film misalignment and light leaks. A light leak produces a red/white blurring on the final image. Often this was used to produce artistic images. This style of photography became known as lomography. The images below reproduce the effects that could be obtained using a Diana camera complete with light leaks and spooling holes.
