London artist Abigail Reynolds has a very interesting take on photography. She folds two so they become overlapping images. She takes care in making the contradictory images form a perfect arrangement. The images are of the same place but taken at different times, one of the modern urban city landscape and one of an earlier time. They two colliding images juxtapose the past and present, highlight the changes that have affected the architecture.
