I never saw that image before, and it's obviously fake. You just can't see through that much seawater.

[thyrsus]

I've seen the image several times, and I'd always assumed it was a painting, using photo-realist techniques.

[protomyth]

Yeah, I thought it was someone that does the background painting for movies. The physics of taking that photograph just didn't seem possible.

[Animats]

It would be a real challenge to actually photograph the entire underwater part of an iceberg. It's probably never been done. If you could find one in clear water, and set off some enormous set of flashes underwater, it just might be possible. That would be a good project for National Geographic.

[protomyth]

I'm not sure the local whale population would be too happy with setting off something underwater to generate that much light. Would be interesting, though.

It's also lit from below, because you know, the ocean floor is bright and reflective.

[afterburner]

And the bottom of such a huge iceberg can't possible be as well lit as if the sun was hitting it from below. (And of course it looks like that because it's an above water shot, flipped.)

Doh. I was imagining him actually flipping an iceberg upside-down for some reason.
