Since it was opened in 1949, the George Eastman House has helped tell "the story of photography and motion pictures -- media that have changed and continue to change our perception of the world." The museum's homepage offers a number of interesting resources about current exhibitions and longstanding collections. One of the more substantial sections of the Web site is titled Education & Research; it contains a couple of video clips of photographic processes, as well as insights into the work conducted at the L. Jeffrey Selznick School of Film Preservation. The site also contains a Timeline of Photography, which describes many remarkable events over the past three centuries. Several sample images of photographs from the George Eastman House collections are available for viewing.
