I don’t recall where I found the link to Dave’s site, but this image jumped out at me. After I dried myself off, I axed him about the colors, and here’s his response:
“Thank you for the feedback! It is funny that you see amazing color where I see too much green and blue! I don’t think the turtle was fluorescent; and while I don’t recall it being quite as bright greenly splotched, the camera often sees things differently than we do underwater, particularly when a flash is used. This is because water “absorbs” the colors of sunlight, the deeper you go, and thus things do not look as colorful in natural light to the diver. However, if you are close enough to use a flash, the white light from the flash “adds back” the color that has been filtered away from the sunshine.”
Adjust your nitrogen level, Dave. It’s a great photo. Just don’t lecture me about ugly dogs, okay?

It DOES look like a Tron turtle.

Impressive – that is one area of photography I haven’t tried. There are sharks down there! And Cthulhu!

The turtle shot you see here was taken with a point and shoot camera. I used a “better” camera with an external flash for another turtle shot which is on the blog and colored more like you’d expect a turtle to be colored.
Archiearchive FCD, yes, there are sharks down there, and I have a few nice shark pictures on my blog. Sadly, it is very difficult to find a shark these days, unless you are in a regular feeding zone or have chum in the water. They are beautiful animals, with much more to fear from us than we of them.
