The device is the image forming device, and a photographic film or
electronic image sensor is silicon the detection means. The media may be the
respective film itself, or a digital electronic or magnetic.
Photographers control the camera and lens to "expose" the recording
material (such as film) to the amount of light needed to form a "latent
image" (the movie) or "raw file" (in digital cameras) which,
after proper processing, it becomes a usable image. digital cameras use an
electronic image sensor based on light-sensitive electronics such as charge
coupled device (CCD) or complementary metal oxide semiconductor (CMOS). The
resulting digital image is stored electronically, but may be reproduced on
paper or film.The chamber (or "dark chamber") is a dark room or living room from which, whenever possible, exclude all light except the light forming the image. The object photographed, however, should be on. The cameras can range from small to very large, an entire room, which remains dark, while the object being photographed is in another room where it is properly illuminated. It was common for photographic reproduction of the copy of background when significant negative films were used (see photo processing). A general principle known since the birth of photography is that the smaller the camera, the brighter the image. This means that when the photographs became sensitive enough (fast enough) to take candid shots of gender or call, detectives used small cameras, some of them disguised as a tie pin that was actually a goal, as a piece of luggage or even a pocket watch (the Ticka camera).
The discovery of "dark chamber", which features an image of a scene is very old, dating back to ancient China. Leonardo da Vinci mentions the camera obscura, which consist of dark natural caves on the edge of a sunny valley. A hole in the wall of the cave acts as a pinhole camera and project a mirror image side face down on a piece of paper. Therefore, the invention of photography was really interested in finding a way to establish and maintain the image in the darkroom. That is, in fact, held the first use of the reproduction of images without a camera when Josiah Wedgewood, the famous family of potters, obtained copies of the paintings in the skin with silver salts. As there was no way to fix, that is, the image stabilization by washing the unexposed silver salts, turned completely dark to light and had to be in a room dark to see.
Renaissance painters used the camera obscura, which effectively gives the optical color reproduction that dominates Western art. The camera obscura literally means "dark room" in Latin. This is a box with a hole that lets in light and create an image on the sheet of paper.
The video camera is a type of camera that has a rapid sequence of photographs on strips of film. Unlike a camera that captures a snapshot at a time, the camera takes a series of images, each called a "frame". This is done through an intermittent mechanism. The frames are later played in a movie projector at a specific speed, called the "frame rate" (number of frames per second). Seeing the eyes of a person's brain to combine the separate images to create the illusion of movement.
