I'll admit, a lot of this image is thanks to luck as I was sitting looking through a window under the water and just hoping that someone would jump/swim into this shaft of light and not be blocked by another swimmer or bubbles. Finally worked out after about 45 minutes of waiting.
Thank you very much. I'm glad that it worked out.
Awesome composition, the lower swimmer looks as if he's being spotlighted. I'm not left wanting anything more; the gentle light on his torso and legs, as well as the gleam on his goggles is simply amazing.
