Take 5: National Camera Day

June 29 is National Camera Day, a day to celebrate how the incredible power of photographs has changed the world. Photographs have allowed us to learn and observe so many things about the natural world that we couldn’t before the invention of the camera.

In honor of National Camera Day, here are the Grand Prize Winners from the last five years of the Picture This: Your Great Outdoors Photo Contest.

The 2016 Photo Contest is now open for submissions! Show us your best photographs taken in Massachusetts (or at Mass Audubon’s Wildwood camp in New Hampshire) that show off everything from wildlife to scenic landscapes to people enjoying the wonders of nature.
