I hopped off my bike to watch a flock of eight to ten ibis peck around in the swamp water in search of a meal. Then I decided to take a seat on the ground and just watch to see if any action developed. The scene presented a few photographic challenges: the birds were in constant motion. Think: high ISO and fast shutter speed. There were so many of them, that they never seemed to form an orderly or symmetrical composition. Think: I’m going to watch for a composition to form, but most likely crop later. The brightness of the birds and the dark water would foil my camera’s efforts to calculate a good exposure. Think: Meter the exposure directly on the bird; you don’t want the feathers to be blown highlights that cannot be recovered in processing.
The result: I caught a scene with some action. One ibis was acting like the bully on the playground, chasing away his peer. Preparation paid off. With all the prior analysis of the scene, I was ready to catch the split-second ibis drama.
