Amateur Photographer:

The orcas were now very close and fast approaching a small group of eider ducks on the water. I realised there could be the potential for an action shot, so I tried to concentrate my attention on the eiders, which is easier said than done with five or six black dorsal fins cutting through the water and getting closer. I moved my focus point low in the frame and focused on the closest duck (in AI servo/continuous focus mode).

Suddenly, the eiders looked panicked and scattered in all directions.

This is a great example of something I teach in my class – great photographs often take a combination of hard work, knowledge, skill and luck. This story combines all of those elements.
