From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Photography \Pho*tog"ra*phy\, n. [Photo- + -graphy: cf. F.
      photographie.]
      1. The science which relates to the action of light on
            sensitive bodies in the production of pictures, the
            fixation of images, and the like.
  
      2. The art or process of producing pictures by this action of
            light.
  
      Note: The well-focused optical image is thrown on a surface
               of metal, glass, paper, or other suitable substance,
               coated with collodion or gelatin, and sensitized with
               the chlorides, bromides, or iodides of silver, or other
               salts sensitive to light. The exposed plate is then
               treated with reducing agents, as pyrogallic acid,
               ferrous sulphate, etc., to develop the latent image.
               The image is then fixed by washing off the excess of
               unchanged sensitive salt with sodium hyposulphite
               (thiosulphate) or other suitable reagents.
