 * Theme pack: DOROTHEA LANGE  (1895–1965 · documentary)
 * -----------------------------------------------------
 * A warm silver-gelatin documentary print — softer contrast than Ansel, open
 * shadow detail, the amber cast of aged fibre paper. Detections are plain full
 * survey frames with typeset serif captions, the way a caption sits under a
 * documentary plate.
