Do you mean "Light & Motion"?
Because "Light In Motion" is something completely different!
Their light switches back and forth between what?

BTW, there are also some very nice bio-fluorescence pictures in issue #57 of Underwater Photography Magazine (but see also http://ejlabs.net/tmp/UwP57.pdf) on pages 56-59.

I imagine that in fresh water you need to be lucky to meet one of the rare organisms that fluoresce (and you are not likely to have a big selection of organisms in a quarry anyway, I guess).
Fluorescence is not very common among fish, it's very common among corals, and there are anemones, algae and snails, etc.
In brack water I only found a moss-like algae (looks like a dark red wad of cotton wool) which glowed in orange under UV light.
In a lake I found nothing fluorescing at all.

Translation from Google:
Ultravijoli
After a successful UV cave photography, carried out by Matthew Simonič sifonu Kompoljske 04/17/2010 in caves, we did 27.2.2011 there are video clips of the first UV močerilov and cave shrimp.
For recording we used filters to the light, the lens filter and special glasses that let only the UV and violet component of light.
Taking the rest of the spectrum of light, are beautifully lit up močerilih spots where more concentrated pigment. In the cave shrimps are usually only kleščice shone in individual specimens as well as some internal organs.
Ultravijoli
How do marine animals are seen outside a visible light in the ultraviolet electromagnetic waves?
Some plants and animals contain proteins, symbiotic microorganisms, etc., which glow fluorescent when illuminated by UV light.
In the passage, some subjects with nocturnal UV seabed.

Funny translation. That ''močeril'' is Slovenian endemite species also known as ''PROTEUS but it was latley found on all balkan teritory. It is coloured human pink (also called ''human fish'' or black with red gills.
It is most famous from POSTOJNA CAVE
Matej has a very large collection of UV photography.
