You can even take fluorescence photographs in the daytime – with a short shutter speed you can underexpose the ambient light without affecting the fluorescence image.

Excitation filtervs emissionfilter

NIGHTSEA’s fluorescence excitation filters turn your electronic flash into a source of intense blue light for taking fluorescence photographs. The key element is our custom made interference filter that transmits just the blue light you need for underwater fluorescence photography. They are used in conjunction with a barrier filter in front of your camera to record the vibrant images you see in the photo galleries.

All of the underwater excitation filters are priced at $189.00. You can purchase them direct from NIGHTSEA or at Backscatter Underwater Video & Photo. (If you are purchasing only photographic accessories please make your purchase on the Backscatter site.)
