The Glass Between Us, Rebecca’s first monograph, explores the complicated relationship between people and animals in some 25 cities around the world. Photographing predominantly in zoos, aquariums, and natural history museums, she often photographed the captive creatures through some sort of transparent barrier, such as the glass tanks in aquariums, the specimen cases in natural history museums, or the Plexiglas walls of the monkey houses in zoos. Sometimes when the light was right, the glass between us captured the reflection of people responding to the animals, their faces a complicated mix of wonderment and irony, delight and sadness, connection and isolation. Sometimes when the light was right, the glass between us became a window, a wall, and a mirror.
