Bob was a member of the Dee Why Camera Club from 2009 till 2016, including three years on the committee from 2009 to 2012. He was also active in the broader community, serving three terms on Pittwater Council between 1996 and 2012. Bob passed away in 2016.
Bob showed his digital images straight out of camera at club meetings. These unedited images were mostly shot with his go to lens, a Canon 10mm-20mm.
In memory of Bob and his photographic style, the Bob Dunbar Trophy was initially awarded to the club member who submitted the best straight-out-of-camera shot: No cropping, only resizing; no curves or other adjustments; no straightening horizons. In fact, no edits of any kind.
From 2023, the format of the competition was changed: The photos no longer had to be straight out of camera. Instead, the requirement was that they were taken within the local council area that Bob had served for, today's Northern Beaches Council. First, second, and third prizes are awarded for digital images as well as prints, and the overall winner receives the Bob Dunbar Trophy.
