This photographer has done a collection of underwater photos, they have a fashion photography style to them, but with children.

I much prefer the more abstract ones, especially this photo.

I love the clarity of the lower part of the photo, like a snapshot in time that you don't normally see. The child's face emerging through the bubbles. And the hazy surface of the water above.

It was also on her website in colour, but think the contrast in the black and white one work really well.
