Water surface
This photo looks super strange. It’s a swimmer who’s emerging from below the water, but hasn’t broken the so-called surface tension yet. The water surrounds his features like jelly or slime, which kind of makes it look like he’s a SciFi alien in hibernation. Brrrr. If the picture had been taken one second later, it would’ve looked completely different. The water surface would’ve been broken and the illusion would’ve been gone.
