What is Fluoro Diving?
Did you know that the light used in most fluoro torches is between 440-480nm? This range excites the fluorescence of Green Fluorescent Protein (GFP) in marine life. Welcome to the world of fluorescent night diving, also known as fluo diving or glow diving. Here, we see corals, marine creatures, and some fishes glowing in neon colors under UV or blue lights. Fluoro diving is more than a visual treat; it opens up a world of hidden underwater fluorescence. High-energy lights, especially blue light, help us see this beauty at depths over 10 meters. Imagine seeing vibrant corals or glowing fish in their true colors!
This diving practice is also key in marine biology research, helping us understand coral health and the impact of climate change. Let’s learn more about fluoro diving!
Things to Know About Fluoro
- Fluoro diving uses wavelengths of 440-480nm to reveal GFP in marine organisms.
- Blue light is more effective than UV light, especially at depths beyond 10 meters.
- Fluo diving aids in marine biology research and coral health studies.
- Nusa Penida in Indonesia is a popular site for fluorescent night diving.

Introducing Fluorescent Night Diving
Fluorescent night diving, also known as fluo diving or glow diving, is a special way to see the underwater world. It uses UV lights to show marine life in bright, neon colors. This creates a magical sight that’s different from regular night diving.
What is Fluorescent Night Diving?
Fluorescent night diving shows the hidden beauty of biofluorescence under the sea. Marine life absorbs UV light and then shines in colors like pink, green, and blue. This makes fluo diving a unique and exciting experience for those who love the sea.
How Does Fluorescence Work?
The science behind marine fluorescence is fascinating. When blue light hits fluorescent materials, it’s absorbed and then shines back out as longer wavelength light. This light is seen through yellow filters that divers use. Blue light is more effective at making corals glow than UV light.
This makes the underwater world glow in a surreal, neon way.
What Will You See when Fluo Night Diving?
When you go fluorescent night diving, you’ll see marine life glowing in bright colors. Places like Bonaire, Grand Cayman, Indonesia, Maldives, and the Red Sea are great for this. Nusa Penida in Indonesia has a special diving package that includes everything you need.
Underwater, you might see glowing corals, anemones, nudibranchs, cephalopods, and scorpion fish. This glowing light shows us the secret lives of sea creatures in the dark ocean.
Need to Bring for Fluorescent Night Diving
Fluorescent night diving lets us see marine life in bright, glowing colors. It’s a unique way to explore the underwater world. When getting ready, we need to pack the right diving gear.
Remember Lights and Filters
For a magical fluo diving experience, we need the right lights and filters. We must have blue dive lights and UV lights. Also, dichroic filters are key to enhancing what we see. Dive centers like Legend Diving provide the needed gear weekly, making it easier for us.
Excitation Filters
Excitation filters are crucial in our diving gear. They work with our lights to create the blue light needed for marine biofluorescence. A good blue light, costing about $70, paired with a quality filter, is essential for the best effect.
Barrier Filters
Barrier filters are also vital. They block excess blue light, letting us see the fluorescence. We can attach them to our masks or cameras for the best view of the glowing colors.
Blue Light vs. UV Light
Choosing between blue and UV lights is important for a safe, amazing dive. Blue lights are safer and more efficient for biofluorescence. Top brands like Big Blue, OrcaTorch, and Light & Motion make blue dive lights for fluo diving.
| Light Type | Cost | Preferred Brands |
| Blue Lights | $70 | Big Blue, OrcaTorch, Light & Motion |
| UV Lights | Varies | Big Blue, OrcaTorch |
With the right diving gear, including blue lights and filters, we’re set for an unforgettable fluo dive. Let’s dive into this glowing world and make lasting memories.
How Do You Shoot Underwater Photography at Night?
Capturing the beauty of underwater life at night is special. It requires the right techniques and equipment. With the right approach, we can capture the glowing marine life beautifully.
Photographic Techniques
There are many techniques for underwater photography. Knowing them helps us choose the best for our goals.
Wide-angle (Painting with Light)
Wide-angle photography is great for big underwater scenes. It shows off the biofluorescence of corals and creatures. We use light to “paint” the scene, making it glow in the dark.
Macro
Macro photography focuses on small subjects like nudibranchs and seahorses. It highlights their details and colors. Make sure you have a macro lens for low light.
Video
Video recording at night shows the movement of glowing marine life. It brings the underwater world to life. Use continuous light sources for bright footage.
Strobes vs. Torches
Choosing between strobes and torches depends on your style and subjects. Strobes are powerful and preserve colors. Torches provide continuous light for focusing. Using both offers flexibility.
Strobes
- Provide bursts of high-output light
- Ideal for still photography
- Helps preserve natural colors
Torches
- Continuous light source
- Assists in focusing and composing shots
- Perfect for video recording
Fluorescence photography is inefficient, so high ISO cameras are needed. Adjusting camera settings helps capture marine life’s glow. Post-processing can also enhance the images.
Mastering these techniques and using the right equipment leads to amazing photos. We can reveal the hidden wonders of the deep sea at night.
Camera Configurations / Settings
When you dive to photograph, setting up your camera is key. You need to adjust ISO, aperture, and shutter speed for low light and bright colors. This ensures your photos capture the beauty of the underwater world.
Manual settings help balance light, keeping colors vivid. Shooting in raw format gives you more control over your photos. This way, you can enhance the colors and details of marine life.
High ISO settings, f/8 to f/11 apertures, and 1/60s shutter speed work well. Turning off the histogram and adjusting the white balance can also improve color. These tips help capture the beauty of underwater life.
For beginners, these photography tips are a great start. They make diving and photography an amazing experience. Places like Nusa Penida offer a chance to see glowing marine life up close.
Right Time and Conditions to Shoot
To capture the stunning glow of marine life, finding the optimal diving conditions is key. The best time is during new moon phases when the sky is darkest. Clear water and calm currents help the fluorescence shine brightly against the dark.
Good dive planning means working with local dive operators. They know the best times and conditions for the dive site. This ensures a safe dive and clearer photos.
Choosing the right light is crucial. Blue light is better than UV for a brighter glow. New LEDs make it easier to capture the neon colors of corals and marine life.
When planning your dive, think about your equipment. You’ll need a blue light, a night sea Sola, and barrier filters. The right camera settings, like shutter speed and ISO, are also important for clear photos.
For sharp images in low light, use a shutter speed of 1/160 sec. For a creative look, try a longer exposure of 1/8 sec to 1/13 sec.
In short, the right environment, technology, and dive planning make underwater photography amazing. It offers a unique view of the ocean’s beauty.
