Still life is a genre of photography used for the "depiction" of inanimate subject matter, typically a small group of objects which may be either natural or man-made. Steady, fixed, immovable. Eternal, essential, archetypical. This is not old school. This is not new school. This is not a genre. This is not a current. This is not a style. This is drum and bass. This is beat and silence. Wind instrument and percussion. A sign on canvas. Nothing more. Nothing less.
