The photography of Bob Gregson is on exhibit in a show titled "Archi/Abstracts" at the Gores Pavilion in Irwin Park, 848 Weed St., New Canaan.

The exhibition continues through Nov. 7.

Presented by the New Canaan Historical Society, the show features Gregson's photographs of familiar buildings by well-known architects. Originally taken to document Gregson's trips to architectural icons, the photos are shot on the run and thus have an immediate look to them.

"It was not necessary to document the buildings as much as to capture a spontaneous moment that expressed, in a simple detail, the heart and spirit of my experience," Gregson said.

The essence of the building needs to be sized up quickly. "I look for details and characteristics that embody the personality of the building. This can be quite difficult, especially when the experience is three-dimensional and may not necessarily translate into a flat image," he said.

Gregson received a bachelor's degree in fine arts from the Hartford Art School and holds a master's of fine arts degree from the Art Institute of Chicago. His work ranges from large-scale participatory pieces to drawing and photography. He has exhibited nationally, as well as in his home state of Connecticut. He is a Silvermine Guild artist and is the creative director of the Connecticut Office of Culture & Tourism.

The Gores Pavilion is open Friday to Sunday from 11 a.m. to 3 p.m. or by appointment. Admission is free to society members and $5 for nonmembers. For information, call 203-966-1776.
