‘Window with View of the Gowanus Heights,’ a tiny, meticulous diorama by Patrick Jacobs set into the gallery wall, imagines what paradise would look like if it suddenly materialized beyond the fire escape. It is part of the group exhibition, ‘Great Photographs: Scapes’ at Hasted Kraeutler, which includes huge photos of lush forests and burning woods, magnificent aerial views and vintage prints of the 19th century Colorado railroad. But it’s Jacobs’ humble ‘what if’ that really dares to dream big by turning a superfund site into a verdant Eden. (Though July 20th.)
