I wrote about negative space as background in  White Space Negative Space.

But you can photograph subject(s) as negative space — just shoot your subject as a silhouette.

♦Silhouette

  • Expose for background: The background has to be brighter than the subject.
  • You may have to manually focus the lens since the subject is dark.

The best time for shooting silhouette is around sunset or sunrise.
