Not your parents's history of photography, this Web presentation of a public television production is divided into topical features rather than using a more traditional chronological approach. These features include the use of photography in art, as persuasion, to affect social change, in presidential image-making, and the photography of war. Probably the most entertaining area of the site is the Image Lab, where users can experiment to see how cropping can change the meaning of a photograph, and manipulate the digital image of a political candidate. The Image Lab also provides the opportunity to go along with Dorothea Lange on the photo shoot that produced her famous Dust Bowl migrant mother photograph.
