Pinhole cameras can also be constructed by replacing the lens assembly in a conventional camera with a pinhole.
In particular, compact 35 mm cameras whose lens and focusing assembly have been damaged can be reused as pinhole cameras—maintaining the use of the shutter and film winding mechanisms.
The size of the cylinder corresponded with their phonograph cylinder as they wanted to combine the moving images with sound recordings.
Problems arose in recording clear pictures "with phenomenal speed" and the "coarseness" of the photographic emulsion when the pictures were enlarged.
One older use of the term "pin-hole" in the context of optics was found in James Ferguson's 1764 book Lectures on select subjects in mechanics, hydrostatics, pneumatics, and optics.
According to inventor William Kennedy Dickson, the first experiments directed at moving pictures by Thomas Edison and his researchers took place around 1887 and involved "microscopic pin-point photographs, placed on a cylindrical shell".
In the 17th century the camera obscura with a lens became a popular drawing aid that was further developed into a mobile device, first in a little tent and later in a box.The camera that recorded the images, dubbed Kinetograph, was fitted with a lens.Eugène Estanave experimented with integral photography, exhibiting a result in 1925 and publishing his findings in La Nature.Other special features can be built into pinhole cameras such as the ability to take double images by using multiple pinholes, or the ability to take pictures in cylindrical or spherical perspective by curving the film plane.Pinhole cameras can be handmade by the photographer for a particular purpose.
