The thing that most struck me about the Zulu dancers we watched perform at DumaZulu was their tremendous energy level. To express such energy in a picture, I used my shutter speed options to capture contrasting interaction. By selecting a 1/50th of a second shutter speed, I knew that I could reveal detail on the dancers who were only singing. They would offer context for the energetic fellow who was dancing at that moment. His quick motions would be blurred at 1/50th, giving me the contrast I needed to express my idea.
