Katherine Bauer and Joyce Lainé of Le Ratoire film collective return to NATURE Lab and the Sanctuary this Saturday, September 20th. Their workshop at NATURE Lab will guide participants in alternative techniques used to develop photographs, which includes using a stew of plants and other natural materials to reveal unique images. In the evening, the duo will present a performative screening of their 16mm films and others produced by the collective. HMM producer Carolyn Tennant talks with the artists about Le Ratoire, their favorite plants, and their upcoming visit.
