Photographs From The 1920's If any period can be said to have encompassed the full potential of photography it would have to be the era between the two World Wars. Some 80 years after the medium first appeared, photographers and their patrons discovered forms and uses for camera images that imbued them with exceptional inventiveness and immediacy. Photography was not only enriched by expanded roles in journalism, advertising, and publicity, but it was nourished also by acceptance within avant-garde movements in the graphic arts. In fact, it might with justice be claimed that except for holography all later directions were foretold during this period.
