Photography uses foremost radiation in the UV, visible and near-IR spectrum. For common purposes the term light is used instead of radiation.<br /><br />Light reflected or emitted from objects form a real image on a light sensitive area (film or plate) or a FPA pixel array sensor by means of a pin hole or lens in a camera during a timed exposure. The result on film or plate is a latent image, which is developed into a visual image (negative or diapositive). An image on a paper base is known as a print. The result on an FPA pixel array sensor is an electrical charge at each pixel which is electronically processed and stored in a computer (raster)-image file for subsequent display or processing. Photography has many uses for business, science, manufacturing (f.i. Photolithography), art, and recreational purposes.</div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1935594004934576227-1754573209191510940?l=my-black-and-white-photography.blogspot.com' alt='' /></div>Betty Lesliehttp://www.blogger.com/profile/07086734719753557030noreply@blogger.com4
