field and field of view

field and field of view
   A background area or an entire physical plane, often of one color and/or texture. Also, a sphere of activity, or a content, or a discourse. And, the area in which an image is rendered by the lens of an optical instrument; also called field of view, which can be any sort of shape and size. A wide field of vision might be panoramic, and a narrow one "long" or "telephoto," high and wide might be "fish-eye," "close-up," a "blow-up," or an "enlargement." Extremely narrow fields of view are routinely achieved with microscopes and telescopes. The latter include the sort of lenses used by satellites that make photographs of small areas of the earth's surface for military, scientific, and commercial purposes. A U.S. Navy Lieutenant, Joe Dalton, is credited with being the first, in 1998, to use a term for this extremely narrow field of view: the "soda-straw effect."
