A Blacklight experience

[Zoaelite]

Anyone ever grab a black light and shine it over the corals at night? I was told that it would be very similar to actinics but WOW, what a surprise. I'm going to take some more photos tonight when the room is dark. This acan during the day is teal and red.

I seem to recall a Reefkeeping article a while back describing a neat photographic technique for corals using black light, very long shutter speeds and a black spatula of all things. The results were quite astonishing.

Buy one of those cigarette lighters with a blue LED light on the end.
Make sure the room is totally dark; no indirect lighting coming from outside or in the house.

It is 5 times the experience you saw but don't trip and fall on anything.

Some corals fluoresce. Some look brown by day and under ordinary reef lights but not under the blue LED

When that kind of light hits a coral, the coral produces and "enzyme" that causes the florescence.

In September last year it was discovered that some fish fluoresce.
