What Is a Photograph?

David Pogue’s Photoshop and Photography: When Is It Real? continues the discussion sparked by the March issue of Popular Photography in which Miriam Leuchter wrote an article titled “What Is a Photograph?” In the magazine’s Reader’s Photos Contest the winners in two of the categories were composites, or Photoshop jobs:

One photo shows a motorcyclist being chased by a tornado; another shows a flock of seagulls wheeling around a lighthouse in amazingly photogenic formation. Neither scene ever actually existed as photographed.
