During that time his hobby of photography became a passion leading to three one-man shows in New York galleries. In 1984, Berenholtz left architecture to pursue a full-time career as a commercial photographer.

In the past 17 years he has had three photography books published: ‘Manhattan Architecture,’ ‘Inside New York’ and ‘Panoramic New York.’ He has produced what he considers to be one of the most comprehensive collections of photographs of New York.
