The public is invited to meet the artist at a reception during the Amherst Art Walk, Thursday, June 1, 5-8 p.m. This retrospective of the Belchertown photographer’s work will include both representational and his recent more abstract imagery. Gambaro’s wanderlust has taken him literally from the most northern reaches of our planet, the Svalbard Archipelago, where he has captured images of polar bears, to the most southern, the Antarctic peninsula, represented by penguins. But he has also recorded beauty much closer to home in the Berkshires and the Quabbin Reservoir, even a nascent oak tree from his own garden. Several pieces from his recent exploration of the Western canyons will be shown in the Burnett exhibition for the first time.
