Photography

Hi distinguished steemians, today we will be learning about photography, sometimes I wonder how life would have been without photos,is it the nostalgic feeling you get when you come across an old photo of yours making small huts with sands that must have been washed ashore by water at the beachside or that old wedding picture of your parents when they were still very young and newly in love, or was it that picture you found under your locker where you and your high school friends where playing basketball,the importance of Photography are just too numerous to mention here,
Firstly let's know the meaning of photography.
Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.

Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Photography is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
