Octoporn. I would have preferred a different category for this image, but these mating Octopus blend into the reef and rock so well that the image is too busy. I used brushes to try and obliterate the rocks and release the Octopus from them..

Origin. Actually, just an urchin.

A Sailfin Blenny displays his distinctive trait.

"Natural Colors" just the background is been manipulated (minimally) to remove almost all of the colors and leave it neutral so the dragons stands out in its natural colors

Not much manipulation required. I have uploaded the one with the original water color as well so you can compare. I just used the curve tool on the already burnt sun burst and then dodged a bit the rest of the water around the dragon...

'Radiance' - A black background was created in post-processing to showcase the brilliant colors of this Caribbean reef squid.

2016 Socorro Islands.Beauty is in the eye of the beholder with this Giant Pacific Manta Ray. This is actually a screenshot that I got from one of my videos off of my PnS camera (TG-4)

If you could coax a Cuttlefish up into the shallows of the reef top you could get this shot,. the setting are the same, lens. etc. This took two images and some layering though
