History
History (from Greek ἱστορία, historia, meaning "inquiry, knowledge acquired by investigation") is the study of the past as it is described in written documents. Events occurring before written record are considered prehistory. It is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Scholars who write about history are called historians.
Photography

Photography
You put your camera around your neck in the morning, along with putting on your shoes, and there it is, an appendage of the body that shares your life with you. The camera is an instrument that teaches people how to see without a camera.
Dorothea Lange, as quoted in Dorothea Lange : A Photographer's Life (1978), p. vii
