Space and Geometry

Elliott Erwitt once said, "To me, photography is an art of observation. It's about finding something interesting in an ordinary place..." I believe it depict an important mission of a photographer. "Space and Geometry" is my architecture series to investigate symmetry and geometry in the urban landscape. I am trying to examine the relationship between space, architecture and human. Does architecture define the space we live in? Why do we have geometry in architecture / space? Does human factor play a part in defining space that we live in?
