"Ours is a time of the machine, and ours is a need to know that the machine can be put to creative effort. If it is not, the machine can destroy us. It is within the power of the photographer to help prohibit this destruction, and help make the machine an agent more of good than of evil. Though not a poet, nor a painter, nor a composer, he is yet an artist, and as an artist undertakes not only risks but responsibilities. And it is with responsibility that both the photographer and his machine are brought to their ultimate tests."
— Dorothea Lange, American photographer, born 1895
