This 
  model creates the space of an event (a woman watering a plant) through its action. 
  Two depth of field shots, each looking at the event from opposite ends were 
  morphed to form the space. A depth of field shot combines all the actions of 
  the event within the observation frame. To observe this a 3D frame containing 
  190 screens was created. Each shot was allocated 95 screens, half the numbers 
  of frames each shot contained (190). The shot would travel from its starting 
  point to the other end and then return to its starting point. Although both 
  shots would begin at opposite ends they would be synchronized in time. Each 
  frame of the shot represents an instance of the space at that time. By projecting 
  each frame onto an adjacent screen and leaving a trail of older frames decreasing 
  in transparency behind, the new construction describes the space of the event 
  as a residue of the action.
