At Peckham Platform, she re-visits her on-going project of the mobile studio which draws on histories of portraiture; and Victorian photographic styles and techniques. Referencing Victorian photographic practices, Perrier positions her sitters in place, using a headrest. Her work explores histories of photographic materials, technologies, formal conventions, and visual strategies. One of the photographs exhibited at Peckham Platform is of a young girl: an adult's hand reaches in, unexpectedly, from the left-hand side of the portrait, as if to steady her. Perrier narrates how this kind of image is part of the documented visual archive of nineteenth century photographs of children. The reaching hand reveals, inadvertently, the artifice that was at play in Victorian portraiture, and the necessity (informed by technologies of the day) of keeping absolutely still.
