The American photographer Ansel Adams pushed the mechanical process of photography into an art form during the 1920’s. Adams’ method was to work backward from the image he had visualized within his mind and then anticipate the moment when the light and subject could be seen at their most illuminating. During Adams’ day, color photography was considered crass, as color photography was thought not to contain nuance and the subtlety which matched the real world. Black and white photography allowed for a beautiful range of tonalities which was abstract but still considered to be realism artwork during the period. Today, with much more sophisticated technology and color materials, the world can be photographed accurately with many different nuances. Ironically, black and white now appears as an abstract artistic medium in comparison to full color photographs
