[Leica] IMG: moon jellies . . . in 3D?

[abridge at mac.com (Adam Bridge)]

We were at the Monterey Bay Aquarium over the weekend. Of course we checked 
out the jellies exhibit.

To me there is a dimensionality to this image that just pops it off the 
screen. I think it's something to do with the contrast between the blue glow 
of the water and the stark white tentacles or whatever that is trailing 
behind. I've linked to the largest size image (although the full-size image 
is there if you wish to see it) because that's where this visual effect 
seems the most pronounced.

Shot at ISO 400, NEX-7, CV 35mm f1.2 (which really works wonderfully well on 
this camera).

Do you see a hint of the 3D effect or is it just me?

Thanks for looking.
