Fluorescence (or "fluoro") can be seen by using a dichroic "excitation" filter on your strobe or light, and a yellow "barrier" filter on your mask and in front of your camera's lens. Many different types of corals and creatures fluoresce—get out there and explore!
Spice Up Your Night Dive
If you're looking for something new on your night dive, check it out. You'll need to put special filters on your lights and on your camera lenses. But if you think the colors go crazy when you turn on your dive light during a night dive, wait till you see what fluorescence does. These colors will be unlike anything you've seen before.
The fluoro night diving experience can be disconcerting initially. Any fluorescing hard corals will be visible - and very bright - even from distances. Meanwhile, anything that is not fluorescing (most of the reef) will be almost invisible. Turning on a standard white diving light will show you the whole scene but totally kill the fluoro mood.
We're actually seeing proteins fluorescing, and this can be hard corals, soft corals, invertebrates, even certain fish. If you're looking for something new, check it out!
