Photography and Cameras
The most important thing to photography is light. The camera is a precise instrument for capturing light. The word camera in Latin means room. The name camera comes from the first invention towards capturing the world on film, the camera obscura or dark room. This invention came about in the 14th century and was used by such artists as Da Vinci and Michelangelo to more accurately draw their subjects onto paper. The invention of this box, made way for more advancements in cameras and photography. There are five essential items in cameras that make photography possible. They are exposure, refraction, plane of focus, angle of view and aperture. Exposure is the amount of time a camera lets film be exposed to light. Refraction is the bending of light through the lenses of a camera. Plane of focus is the area where light reforms an image in the film. Angle of view is the angle created on a lens when you take the two most outer points you can see through a lens and diverge them to the exact center of the lens. The angle created will be the angle at which the camera can take pictures at. Aperture is the amount of light a lens allows into the camera. The camera obscura, as mentioned previously, was a large
Digital photography took the world by storm in the 1990's and was starting to quickly replace the conventional camera in the field of photojournalism and advertising. Digital cameras are now readily available to the general public for a couple of hundred dollars. There are more sophisticated types of digital cameras the professional photographers use. These work just like SLR's, but record the picture in a set of ones and zeros via a scanner instead of using 35mm film. All digital cameras use the binary system to record their pictures. Amateur photographers use digital cameras in the same way as a PAS camera. The more sophisticated the camera, the higher the resolution, that is the amount of pixels there are in the shot, is. A pixel is a digital dot of color created by a series of ones and zeros. Also the higher the resolution, the more money it is. Cameras have been with us since as early as the Civil war and have flourished ever since. As the technology expands so will the capability of how well a picture will become. There has been more of a jump to the digital side lately, but there still is no comparison, yet, to the quality and freedom of conventional cameras. Most people have been taking pictures since they were kids and cameras and photograph has been a major part of American culture because of it. Not only is it a pa
