Look at the world beneath the waves in an exciting new way with this Ikelite Yellow Barrier Filter, which fits flat lens ports for their underwater DSLR camera housings. This accessory allows you to use your existing photography setup, including the camera, housing, and lights, to capture the brilliant fluorescent glow emitted by coral, jellyfish, and other sea life.
Fluorescence is mostly visible in greens, blues, and reds, and is often produced as a result of exposure to a particular wavelength of light. Fluorescence photography is best done at night or at depths great enough to block out sunlight, but it's possible to do it in more shallow water during the day by experimenting with filtered light sources and underexposing the ambient light. For best results, combine this filter with a separate one for your flash or video light, and add a third for your dive mask so you can see the effects first-hand with your own eyes. This Yellow Barrier Filter can be removed and replaced while underwater.
