While setting up this photograph a duck trotted into the scene, quacked, sat down, and upon not hearing the shutter click, got up and moved, quacked and sat down again. This happened several times as he moved from l to r across the ground glass. He then, upon still not hearing a shutter click, did the same from r to l several times. I obliged at that point, and gave him a resounding shutter click. He moved away at last. It was the most bizarre experience I've ever had making a photograph. I do have a shot of him..the last one I took, but he just doesn't belong in the final print. Oh well....what the duck.
