This is not a real situation. This is a snapshot shot captured during an outdoor filming of a TV channel.

Miss Linda Chung, one of the Miss Hong Kong, is performing in this filming.
I accidentally met this filming while I was taking some snapshots around Ocean Terminal in one evening.

It was very dark at that time and I did not want to use a flash to disturb her performance. So the only option is the combination of high iso and my 135 L.
