Extreme Depth of Field at High Focal Ratios

This 3-second exposure on Tri-X film was made through 1 mm pinhole to produce an effective focal ratio of f/85. The view shown is the equipment area of the Department of Physics and Earth Sciences. Notice the near objects to the right of the camera are in focus, as are the more distant objects in the long room.
