Make a Pinhole Camera workshops are offered this summer at Penobscot Marine Museum. The cost is $10 per person, $7 for museum members. Make a Pinhole Camera is open to all ages, but young children must be accompanied by an adult.

The workshop will be offered twice: Thursday, July 23; and Thursday, Aug. 6, both from 1 to 4 p.m. For more information or to sign up, call 548-0334 or visit penobscotmarinemuseum.org.

A pinhole camera is a camera without a lens and with a single small aperture — a pinhole. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box where a piece of film or photographic paper is wedged or taped into the other end. The ethereal images made with a pinhole camera seem magical.

Workshop teacher Anne-Claude Cotty of Stonington is a photographer, artist and teacher. She has taught at Haystack Mountain School of Crafts, and her work has been exhibited at the University of Maine Museum of Art, Colby College Art Museum and the Portland Museum of Art.

Make a Pinhole Camera is part of “Exploring the Magic of Photography: Painting with Light,” Penobscot Marine Museum’s first major exhibition of historic photography. It includes four exhibits, a walk-in camera, a wall of selfies taken by museum visitors, an historic darkroom, tintype and cyanotype demonstrations and the workshops on making pinhole cameras. The four exhibits — “Through Her Lens: Women Photographers of Mid-Coast Maine, 1890-1920”; “Twenty Best”; “Evolution of the Photographic Snapshot: 1888-2015”; and “The Carters and the Lukes – Selections from the Red Boutilier Collection” — are filled with interactive opportunities for visitors including life-sized photographic cut-outs with which visitors may photograph themselves, an online exhibit of visitor photographs and comments and QR codes and tablets providing access to audio clips of interviews, biographies, and commentary by historians, curators and professional photographers.
