OK - this stuff is too cool, so here's another blast of fluorescing coral photos (today we're doing all vertically oriented photos).

One extra cool thing to note in this batch... the top photos on either side show a closed coral and the same coral with its feeding polyp tentacles opened. Pretty awesome, no?

Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM with Yellow 12 Filter, 1/120th sec at f/8. Image Stabilization on. ISO 640. Ikelite Housing and Port with dual Ikelite 161 Strobes in TTL Mode both with NightSea BE3 Excitation Filters. Raw conversion in Photoshop CS5.

The second photo on both sides appear to be two different types of brain coral. One of the fun things we like to do during night dives is feed blood worms to the brain corals - I don't have any photos of that, but I do have a shot of an arrow crab catching a blood worm that I will share soon!

Stay tuned!
