Schooled on the streets of New York in the instant reflex art of Cartier-Bresson, Robert Frank, and Garry Winogrand, Mermelstein expands upon that iconographic idiom by shooting exclusively in color. His work will be on view at Rick Wester Fine Art, New York. Miller Block Gallery, Boston, will show work from David Maisel's Library of Dust that depicts individual copper canisters, each containing the cremated remains of patients from a state-run psychiatric hospital, and blooming with impossibly colorful corrosions. Library of Dust was published as an oversized monograph by Chronicle Books last fall.
