Commonly regarded as one of the pioneers of motion-picture technology, Eadweard Muybridge carried out several photographic studies of animal and human movement in the late nineteenth century. One of Muybridge's lesser-known commissions was an album of interior photographs that he created in 1880 for his friends Kate and Robert Johnson. This article offers a close reading of this album and argues that it has more in common with Muybridge's motion studies than historians have previously recognized. Far from being a commercial outlier, the album offered Muybridge an opportunity to experiment with the technological and cultural possibilities of photography in a new way. Through ghosts, mirrors, and other forms of representational excess, these images make visible Muybridge's handiwork as a photographer and the intellectual complexity of his collaboration with Kate and Robert Johnson.
