Pinhole Photography

Pinholes can be explained by a simple law of the physical world. When light travels linearly and a part of the light reflected from a bright object passes through a small hole in a thin material they do not scatter and instead cross and cross inversely on a flat surface parallel to the hole It is reformed as an image (Wilgus). Although pinhole has many uses with the passage of time, it contributed the most to photographs. Without pinholes, there are no cameras or pictures we know.

Pinhole images have been seen from the era of Aristotle. He saw that the images and shapes were blinking in a small hole where several leaves overlapped. Pinhole photography captures these images and shapes on film using lenses without lenses. A small hole exchanged the lens. Light passes through the hole and forms an image on the rear wall of the camera. The light goes straight and therefore passes through the hole, so the image is upside down. Looking at the outdoor scenery, the sky is below and the ground is on the top. The pinhole camera may be small or large. They can be made from shell, oatmeal box, film can, soda can or any size box. It is used as a pinhole camera even in large buildings cars and rooms. In the century since the Renaissance, pinholes were mainly used for scientific purposes of astronomy.

The first 'camera' is the camera's black box or pinhole camera. This device in the history of photography is said to be able to go back to ancient Greeks and ancient Chinese. The device projects the image using pinhole, but the resulting projection is reversed. Alhazen or Ibn Al-Haytham is an authority in the field of optics and is said to be known in the history of photography as a person who later produced a pinhole camera in 1000 years later. In the early stages of photography, black boxes of photographs, particularly used in 1544 for the appreciation of food by the University of Leuven Reiners Gemma Frisius, suggested using this device as an aid to scientific painting in 1544 did. In 1685, Johann Zahn conceived the first small portable camera. This is close to a compact camera known today.
