The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly.
Euclid began his study of optics as he began his study of geometry, with a set of self-evident axioms. Lines (or visual rays) can be drawn in a straight line to the object. Those lines falling upon an object form a cone. Those things upon which the lines fall are seen. Those things seen under a larger angle appear larger.
The optics of photography involves both lenses and the medium in which the electromagnetic radiation is recorded, whether it be a plate, film, or charge-coupled device. Photographers must consider the reciprocity of the camera and the shot which is summarized by the relation
Vision of humans and other organisms depends on several organs such as the lens of the eye, and any vision correcting devices, which use optics to focus the image. The eyes of many animals contains a lens that focuses the light of its surroundings onto the retina of the eye. This lens is essential to producing clear images within the eye.
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens, photographic lens or photographic objective is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Reversed achromatic lens. Charles Chevalier's Paris optical firm produced lenses for both Niépce and Daguerre for their experiments in photography.In 1829 [3] [citation needed], Chevalier created an achromatic lens (a two-element lens made from crown glass and flint glass) to cut down on chromatic aberration for Daguerre's experiments.
The American Academy of Pediatrics recommends three full hours of physical activity per day for kids ages 3 to 5, and 60 minutes of moderate-to-vigorous physical activity on most days of the week ...
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 .
