In photography circles, this is what we commercial photographers refer to as a "quadtych."
These four couples portraits were shot as part of an ongoing ad campaign for the Utah Association of Realtors. (Hence, the blue background, which is their corporate color.) The ads feature recent home buyers near Salt Lake City and other places in Utah who benefited from the expertise of hiring a professional realtor. Many thanks to the Intrepid Agency who gave me this opportunity.
