“Guns have a massive amount of power associated with them. They are designed to kill. We decided to photograph portraits of them in a similar way you might photograph a powerful person. Like powerful people, pistols have this “perfect” quality that we wanted to explore. As we started shooting them, we could see flaws in their design. Metal burring around the barrels, scratches in the metal. This imperfection and detail were very interesting to us; connecting us back to these images as portraits”. – Peter Andrew.
