Photo taken aboard the SS Pennsylvania somewhere on the Atlantic Ocean c.1900. See: https://en.wikipedia.org/wiki/SS_Pennsylvania_(1896) for details on this ship. Probably first class passengers, and I think this does give a sense of what life aboard the Titanic must have been like 12 years later.
Arkansas prison, “The Farm”. Maybe not as well known as the Louisiana State Penitentiary at Angola, but a place to stay far away from if possible. Shown here is the water wagon used for the prisoners out in the fields (April 18, 1957). See: https://en.wikipedia.org/wiki/Cummins_Unit for a full explanation of the goings on at Cummins.
All things being equal I believe that most photographers choose to take well focused images. However, there are certain situations where a soft focused image works much better. In the creative world of advertising, motion in a photograph created by blurring or panning adds a new element into an otherwise static, two dimensional image. This practice is also used in sports photography to great effect. But what about photojournalism and documentary photography?
