'Dorothea Lange: A Life Beyond Limits'

I started reading this biography on a trip this past winter:

I saved a few quotes from it. Here are 2 from the introduction that I particularly like:

Most of Lange's photography was optimistic, even utopian, not despite but precisely through its frequent depictions of sadness and deprivation. By showing her subjects as worthier than their conditions, she called attention to the incompleteness of American democracy. And by showing her subjects as worthier than their conditions, she simultaneously asserted that greater democracy was possible.

And here's a bit about "documetary" photography and representation:

The camera's capacity to replicate what the eye can see made it appear, originally, to be the ultimate documentary tool. It seemed to be a machine for exact replication, its products machine-made, until the myriad means of constructing photographs were widely understood. Invented just as art steered toward expressing a subjective vision, an individual inner consciousness, the camera seemed limited to representing that which is visible to the naked eye. Honoré Daumier said that "photography described everything and explained nothing." Photographers engaged in some self-delusion along these lines; Walker Evans called documentary "a stark record ... [of] actuality untouched." Lange did not fuss about exact representation in her photography. Her experience as a portrait photographer left her at ease in retouching an errant hand or shadow, in asking her subjects to move to a different spot or position. Like an historian, she wanted her photographs to emphasize what she saw as the main point and to prevent her viewers from being distracted by details. In her portrait studio she wanted to reveal the inner, not the outer, life and character of her subjects, and she continued the search for hidden truths in her documentary work.
