The last Jump

This evening it had rained and the weather was patchy at best. I decided to walk out light , camera lens and tripod.As the sun set some light crept through allowing some unexpected photo ops but the suprise photo was the last of the day. This is what inspires me about photography.. the unexpected and unforseen.. story as follows
The boys had been swimming and leaping off the jetty. About 10 or 12 year olds. Dad says, common boys lets pack it in. And as they do one younguns pipes up.. "Just one last jump Dad "
I was in position so I quickly bumbed the ISO to 1600 to get some sort of shutter speed in the dying light and waited, camera on tripod, finger on cable release till he launched himself into the air.
I got as much noise out of the shot that I could so ssssh!
