Today, the photographic plate has largely been replaced by computed radiography, which uses photostimulable phosphor plates (PSP plates). In this process, the radiation penetrates the subject, hits the plate, and excites the electrons in the areas where the subject is less dense. This piece of...
First a photographic plate is coated with a light-sensitive material. The plate is positioned so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged and published so that people can study it. Because most astronomical objects are very remote,...
There is no such thing as a Kirlian photography camera. In fact, Kirlian photos are not created with a camera, but with an electrified photographic plate. What is the Kirlian photography aura? While some believe it is the life force of biological material, others claim it’s simply evidence...
Kirlian-Photography is a photographic method that includes scanning a high voltage charge through an object that is linked to a photographic plate. The resulting image typically includes Kirlian energy or Kirlian Effect and colored “aura” around the object. If you’re an interested photographer who...
The process of taking a Kirlian photo is a relatively simple one and does not even require the use of a camera. First, a sheet of photographic film is placed on top of a metal plate. Then, the object that is to be photographed is placed on top of the film. To create the initial ...
However, since information is lost in the photographic process, we cannot reconstruct the 3-dimensional world completely with just one photograph. As a minimum, we require two different photographs to reconstruct the 3-dimensional world. If this process was perfect, the two photographs are more ...
The photographic plate records the visual interference that results from the light hitting the object. It does not capture the object as it appears to the naked eye. In order for holography to work correctly, the light beams must be stable throughout the image capture process, a state known...
First photographic portrait image: In 1839, Robert Cornelius took the first self-portrait using the daguerreotype process. He took the selfie outside his family’s Philadelphia gas lighting business. The photo is a part of the Library of Congress’ Marian S. Carson collection. First-known photogr...
Computer-to-plate (CTP) is an imaging technology which helps to transfer a digital image generated in a computer directly to a printing plate. Before CTP, the technology used was computer-to-film (CTF), where the image output was passed to a photographic film, and the output film was then...
A photograph (also known as a photo) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are created using a smartphone/camera, which uses a lens to focus the scene's vi...
