What camera was used to shoot the award-winning work "Light in the Dim"?

BrianYen, the photographer of "Light in the Dim", became the winner of this year's final award-winning work. Brian said that he often takes pictures with a miniature camera. Many of his photos were taken at night because he had to wait for his little daughter to fall asleep. It stands to reason that this work should also be shot in a micro-single.
