My Fuji XE-1 helped make the colors look eye popping and true to reality. Yes, these corals really are that intense! The big purple coral is called Red Dragon. The green one in the lower right is a Montipora species- similar to Capricornis but not quite the same. The round one directly above the Monti is an Echinophyllia known as the Vivid Echinophyllia. Finally, that incredible flourescent screaming green Acropora is Acropora Caroliniana.
Some technical notes on the photography side of things: I used a 60mm macro lens and sturdy tripod. Camera settings: ISO 200, f16, 1/25 shutter speed. Comments, questions or critiques are welcome!
