Going for the Goal at ISO 6400
An outside-mid soccer player makes the corner for the goal.
When shooting sports in steady lighting conditions, I usually establish a manual exposure with a wide open aperture (to blur the background and gain a faster shutter speed) and a shutter speed sufficient to stop the action. In this case, 1/800 at ISO 3200 was not good enough. So, I was using the 50D's emergency ISO 6400 setting. It doesn't look bad at this reduced size - and the image would have been blurred at ISO 3200.
