Thinking of Justin Paton

We were told there was no photography allowed at the National Gallery so when we saw what we thought was a group standing in front of a painting all taking photographs in unison, we took one of our own. After being ticked off by the guard, we realised that what the members of the group were actually doing was making a square shape with their fingers to create a viewing frame. It was how-to-look-at-a-painting 101.
