  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.
