This month at Galerie BMG in Woodstock, "Hibernus...a winter study," an exhibition of photographs by David Ellingsen. Using Polaroid 55PN film, Ellingsen shot a series of plants at the end of their life cycle. Medium and message form a strong metaphoric bond in this work—the 55PN, a fine-grained, textured film that's open to imperfection and mutation during the development process, was discontinued by Polaroid in 2008. "Hibernus...a winter study" opens on December 4 and continues through January 11. (845) 679-0027; www.galeriebmg.com.
