Fluorescence night diving is also referred to as fluo diving or glow diving. Fluorescence absorbs high energy light and re-emits it as low energy light. This is different from phosphorescence which has the capability to store light and re-emit it over a longer period of time.
When fluo diving, blue lights and yellow lens filters for your mask enhance the stunning colors and unbelievable beauty of the underwater world. Many of the critters and corals will be worth a second look as they glow in hues of pink, green or blue.
These pictures are taken at Wakatobi, SE Sulawesi, where I had my first experience of fluo. On my first fluo dive, my diveguy and I didn’t move more than 10 metres from the boat, we were so blown away by how different it was.
