Perspective is an interesting thing. Everyone has their own, and they can all be manipulated. Sometimes we realize the manipulation is occurring — but most of the time, we're naive to the fact that we're being manipulated at all.
Every piece starts as a straight architectural photograph before the manipulation begins — angles mirrored, extended, or folded back until the space stops behaving the way the real building did. The edit is never hidden; the point is noticing exactly where the photograph ends and the reconstruction begins.
