The Origins Of Photography, Early Photographic Processes, The Evolution Of Cameras, Early Uses Of Photography

Photography is the art and science of creating images using light. For most of its history, this has usually meant using silver compounds that darken when exposed to light. With the growth of computers, photography can also be done with electronics that measure light intensities and create images based on them.

The invention and perfection of photography has affected many areas of life. Of course, nearly every family now has albums full of snapshots, portraits, and wedding photographs. But photography is also an integral part of the modern printing, publishing, and advertising industries, and is used extensively for scientific purposes. Motion pictures consist of a series of photographs, taken at the rate of 24 per second.
