Vertigo

Photographer Jun Ahn, from Seoul, South Korea, has travelled to the top of some of the tallest buildings in her native city, New York and Hong Kong. Once she has climbed to the top of one she will find a suitable location, sit or stand dangerously close to the edge and pose for self portrait photographs.
