Kirlian photograph of two coins. Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.

Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the " VNIR ".
This photograph of the Library in Combermere Abbey was taken by Sybell Corbet in 1891. Spirit photography started appearing in England in 1872 from photographer Fredrick Hudson's studios. [2] He allegedly "gimmicked" his camera to hold a pre-exposed image that would move into place when he took his photo. [4]
While it was not until 1981 that the first consumer camera was produced by Sony, the groundwork for digital imaging and photography had been laid. [ 21 ] The first digital single-lens reflex (DSLR) camera was the Nikon SVC prototype demonstrated in 1986, followed by the commercial Nikon QV-1000C released in 1988. [ 22 ]
This allows the camera to use a longer exposure and/or a longer focal length lens or even be attached to some form of photographic telescope co-axial with the main telescope. Telescope focal plane photography. In this type of photography, the telescope itself is used as the "lens" collecting light for the film or CCD of the camera.
In photography, backscatter (also called near-camera reflection [1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust, water droplets, or other particles in the air or water. It is especially common with modern compact and ultra-compact digital ...
In 1991, Kodak unveiled the DCS 100, the first commercially available digital single-lens reflex camera. Although its high cost precluded uses other than photojournalism and professional photography, commercial digital photography was born. Digital imaging uses an electronic image sensor to record the image as a set of electronic data rather ...
Photography – process of making pictures by the action of recording light patterns, reflected or emitted from objects, on a photosensitive medium or an image sensor through a timed exposure. The process is done through mechanical , chemical , or electronic devices known as cameras .
