This is a striking image. I'm thinking this was either done by continuous multiple exposure or that it was manipulated in post processing. Either method, it has made this image amazing to look at. I love the monochrome and the fairly high levels of contrast; it gives this image that extra 'punch'. The series of that man jumping is great to look at the journey from about to jump to entering the surface of the water. It's rather fascinating. It's like a mini-movie in whole photograph.
