One of my colleagues does aerial silks as a hobby. Her school had a showcase on Saturday. It was a really fun, and impressive, event with an 80's theme. All the silks were actually quite secure, and no-one was in danger, but the expression on this performer's face looked a bit anxious, so I thought it was appropriate for the challenge. The lighting in the gym was terrible, though. This was one of the lower ISO shots. I had quite a few at ISO 25,600 (with my F2.8 zoom)
