Our cruise was followed for several days by flights of Boobies, a bird that hunts fish by diving from a height into the sea and pursuing their prey underwater. This one was flying just below the balcony of my own cabin, and I was not only able to capture it in flight, but in doing so, I introduced a sense of motion that contradicts the actual stoppage effect. It is this contradiction that creates almost a vibrating effect – both the brilliantly deep blue sea and the bird appear to be throbbing with energy.
