Room Gallery continues its Emerging Artist Series with A Just Noticeable Difference, a video installation by Kenny Berger.  The work’s title comes from the 19th century psychologist Gustav Fechner, whose experiments addressed the minimum change in sensory input that a person could detect.  Berger’s video installations have long been concerned with the limits of sensorial perception in art, influenced by the work and writings of Robert Morris.  Departing from classic Minimalism, however, Berger’s installations incorporate film and narrative in order to address a given historical event.  In this case, it is the uncanny arrest and conviction of the artist’s childhood neighbor, Lenny Berg, a securities broker who was caught running guns to Poland in 1984.  Perceived by the artist as a “double” or “mirror” of what we think to be normal, the case of Lenny Berg is an overture to consider the broader subject of what constitutes the “real” in both art and life.
