I love the works of Florian Maier-Aichen. Experimenting with traditional and digital photography, Maier-Aichen invites the viewers to contemplate our perception of what is real and what we believe to be real. The artist creates a world where fact and fiction exist together and constructs a reality that makes us question what is right before our eyes. See his works on the Saatchi site:
