I think it's just an example of how good digital cameras have become. First off, it's and obvious telephoto effect bringing objects closer together than the actually are, secondly clearly it's a high shutter speed in order to freeze the moment. Thirdly, what a lucky shot.
The sheer quality of digital pictures is amazing long since surpassed the quality of even the best slides. That's not a photoshop. It's just a crop which retains the quality. Someone took a portrait photo of me recently with digital. When I zoomed in on my eyeball. I could actually see the reflection of the photographer in my eye. Amazing.
