I ask myself because this is also what we think of our world, don’t we? Architectural models and art can invoke meditations like this in a photographic investigator, in the most unsuspected moments or places. This one happened in Venice, during the 2016 Architecture Biennale.
Photographically investigating people who aren't real -but they think they are- is a challenge... Who knows... maybe I am being investigated myself right now. How do I know for sure that I am real? When the question really arises, answering it becomes a true challenge... You should try it yourself!
