BANGOR — The University of Maine Museum of Art opens two new contemporary photography exhibitions this month.

Photographer Thomas Hager pays homage to the early photographic processes of Sir John Herschel and Anna Atkins in “New Dawn Fades,” on view June 24 to Sept. 24.

Hager re-examines early historical processes, and employs new techniques and technology to achieve large-scale images. In several figurative works, he finds inspiration in Leonardo da Vinci, Andreas Vesalius and others. The exhibition also features an assortment of botanicals using processes that reflect Hager’s interest in the intersection of art and science.

Also opening June 24 is “Photo National 2011: A Survey of Contemporary Photography.” This show features 76 works by 34 fine art photographers from throughout the United States chosen through a competitive jury process. The exhibition demonstrates the diversity of contemporary photographic processes and various approaches.

Many Maine photographers are represented in the exhibition, including Jeffery C. Becton of Deer Isle, Melonie Bennett of Gorham, Leslie Bowman of Prescott, Anne-Claude Cotty of Stonington, Julie K. Gray of South Portland, Sean Alonzo Harris of Portland, Robert Moran of Bar Harbor, Jim Nickelson of Camden, Dianna Rust of Camden, Sarah Szwajkos of Rockland and Shoshannah White of Portland.

Brian Paul Clamp, director of ClampArt Gallery in New York, and George Kinghorn, director and curator of the UMaine Museum of Art, juried the show.
