Our Best Underwater Strobes
What Are Underwater Strobes?
Underwater strobes are devices that emit short, intense bursts of light to illuminate your subject, bringing out vibrant colors and sharp details that would otherwise be lost underwater due to the absorption of light, with more of the color spectrum being lost the deeper you go. Unlike regular camera flashes, strobes are designed to handle the unique challenges of underwater environments, such as water pressure, saltwater corrosion, and light diffusion.
Underwater strobes are typically used in tandem with underwater cameras or housings. They can be mounted on arms or brackets, allowing you to position the light at different angles for optimal lighting.
Why Do You Need Underwater Strobes?
The best Underwater strobes aren’t just an accessory—they’re a necessity. Here’s why:
1. Restore Lost Colors
Water absorbs light, and as you descend, colors like red, orange, and yellow disappear. By the time you reach 10 meters, everything starts to look blue or green. Underwater strobes bring back those missing colors, making your photos look natural and vibrant.
2. Eliminate Backscatter
Backscatter is the annoying specks or particles that appear in your photos when light reflects off tiny particles in the water. Strobes help reduce this by allowing you to angle the light away from the camera, ensuring your subject is illuminated without the distracting “snowstorm” effect.
3. Freeze Motion
Underwater strobes have a fast flash duration, which helps freeze fast-moving subjects like fish or coral swaying in the current. This is especially useful for capturing sharp, detailed shots in dynamic environments.
4. Enhance Creativity
With strobes, you can play with lighting angles, shadows, and highlights to create dramatic and artistic compositions. Whether you’re shooting a close-up of a seahorse or a wide-angle reef scene, strobes give you the flexibility to experiment and elevate your photography.
How to Choose the Best Underwater Strobes
Not all underwater strobes are created equal, and choosing the right one can make or break your underwater photography experience. Here are some key factors to consider when shopping for the best underwater strobes:
1. Power and Output
The power of a strobe is measured in guide numbers, which indicate how far the light can reach. Higher guide numbers mean more powerful strobes, ideal for shooting in deeper or darker waters. However, if you’re mostly shooting in shallow, well-lit environments, a lower-powered strobe might suffice.
2. Recycle Time
Recycle time refers to how quickly the strobe can recharge between flashes. Faster recycle times are crucial for capturing fast-moving subjects or shooting in rapid succession. Look for strobes with a recycle time of 2 seconds or less for optimal performance.
3. Beam Angle
The beam angle determines how wide or narrow the light spreads. A wider beam angle is great for wide-angle shots, while a narrower angle works better for macro photography. Some strobes come with adjustable beam angles, offering versatility for different shooting scenarios.
4. Battery Life
There’s nothing worse than your strobe dying mid-dive. Check the battery life and charging options before making a purchase. Rechargeable batteries are more eco-friendly and cost-effective in the long run.
5. Durability and Portability
Underwater strobes need to withstand harsh conditions, including saltwater, pressure, and impacts. Look for models made from durable materials like aluminum or high-grade plastic. Additionally, consider the size and weight—compact strobes are easier to carry and maneuver underwater.
6. Compatibility
Ensure the strobe is compatible with your camera or housing system. Some strobes come with TTL (Through-the-Lens) metering, which automatically adjusts the flash output based on the camera’s settings. This feature can be a game-changer for beginners.
