Understanding Underwater Photography Basics

Underwater photography is a captivating but challenging discipline that combines the art of photography with the technical skills of diving. To excel in capturing the vibrant underwater world, it’s crucial to understand the fundamental differences between underwater and terrestrial photography and the essential equipment required.

The Unique Challenges of Underwater Photography: Underwater photography differs significantly from its land-based counterpart due to the aquatic environment’s physical properties. Water absorbs colors, reduces light, and distorts images, making photography underwater more complex. Light behaves differently in water, with colors like red and orange disappearing first as depth increases. This absorption of light results in color loss, which is why underwater photographers must adjust their techniques and equipment to capture the full spectrum of marine life colors.

Essential Equipment for Underwater Photography:

  1. Camera and Housing:

    • Camera: A good starting point is a waterproof camera or a camera with a waterproof housing. For serious underwater photographers, DSLRs or mirrorless cameras within dedicated underwater housings offer greater control over settings and higher quality images.
    • Housing: This is critical as it protects your camera from water and pressure. The housing should be specifically designed for your camera model to ensure all controls are accessible.
  2. Lenses:

    • Wide-Angle Lens: Ideal for capturing expansive underwater landscapes, large wrecks, or groups of marine life. Wide-angle lenses are preferable in clear water where light is abundant.
    • Macro Lens: Perfect for shooting small subjects like fish, coral, and other sea creatures in detail. Macro lenses help in focusing closely to highlight the intricate patterns and textures of marine life.
  3. Strobes and Lights:

    • Strobes (Underwater Flash): Essential for color correction in deeper or darker waters, strobes restore the natural colors lost with depth. They provide a burst of bright light that brings out the vibrant colors of the underwater environment.
    • Continuous Lights: Useful for focusing or during night dives, continuous lights help illuminate the subject, especially in macro photography where detailing is key.
  4. Ports:

    • Dome Port: Used with wide-angle lenses, a dome port corrects for the water’s refraction, allowing for clearer and wider shots.
    • Flat Port: Works best with macro lenses, helping to magnify the subject and capture finer details.

Basics of Camera Settings: Understanding your camera’s manual settings is crucial in underwater photography. Automatic modes often fail to adjust adequately to the unique lighting conditions underwater. Learning to manually adjust the ISO, aperture, and shutter speed will greatly enhance your ability to capture stunning underwater images. Lower ISOs are preferable to reduce graininess, apertures should be adjusted based on the focus depth and the amount of background you wish to capture, and shutter speeds must be fast enough to capture swift marine life but slow enough to allow adequate light intake.

Preparing for Your Dive

Proper preparation is crucial for successful underwater photography. This stage sets the foundation for the quality of your underwater images and ensures a smooth and safe diving experience. Here’s how to prepare effectively for capturing stunning marine life through your lens:

Selecting the Right Gear:

  • Camera and Housing: Ensure your camera and its housing are suitable for the depths you plan to explore. Check all housing seals for leaks in a controlled environment to prevent water damage. It’s vital to use a housing specific to your camera model to access all necessary controls effortlessly underwater.
  • Lenses: Choose lenses based on the subjects you anticipate shooting. Wide-angle lenses are ideal for capturing expansive coral reefs and larger marine life or groups of fish, while macro lenses are perfect for close-up shots of small species and detailed textures.

Familiarizing Yourself with Equipment:

  • Practice Makes Perfect: Before diving into the ocean, spend time with your gear in a pool or calm, shallow water. This practice helps you familiarize yourself with the settings and adjustments needed underwater, which can be quite different from land photography.
  • Control Accessibility: Make sure you can easily access and adjust your camera’s settings through the housing. Practice changing settings like ISO, aperture, and shutter speed quickly as underwater lighting conditions can change rapidly.

Safety Considerations:

  • Dive Plan: Always have a clear dive plan, which includes understanding the dive site, current conditions, and expected marine life behavior. Inform your dive buddy about your photography plans and ensure you both agree on signals for communication, especially if you need to stay stationary for long periods.
  • Pre-Dive Checks: Perform a thorough pre-dive safety check of all your equipment. Ensure your buoyancy control device (BCD), regulator, and other dive gear function correctly and are comfortable.
  • Buoyancy Skills: Good buoyancy control is essential for underwater photographers to avoid damaging the reef or disturbing marine life. If you’re not confident in your buoyancy skills, consider taking a refresher dive or a buoyancy specialty course before attempting complex photography dives.

Mental Preparation:

  • Setting Expectations: Be patient and keep your expectations realistic. Not every dive will yield perfect shots, and marine life encounters can be unpredictable.
  • Environmental Awareness: Maintain a high degree of environmental awareness. Be mindful of your surroundings, avoid touching or disturbing the reef, and ensure you do not stress the marine life with your presence or equipment.

Camera Settings for Underwater Photography

Underwater photography poses unique challenges due to the differing light conditions and water’s optical properties. Mastering your camera settings is crucial to obtaining clear, vivid photographs under the sea. Here’s a guide to the essential settings you should know:

Manual vs. Automatic Settings

  • Manual Settings: For experienced photographers, manual mode is recommended underwater because it allows complete control over the exposure. Water absorbs light, especially colors like red and orange, which diminish as you go deeper. Manual control helps you adjust to these changing conditions dynamically.
  • Automatic Settings: Most modern cameras come with underwater modes, which are good for beginners. These settings automatically adjust for the lack of red light but often can’t account for all underwater lighting challenges like backscatter (reflected particles in the water).

Recommended Camera Settings

  • ISO: Keep the ISO as low as possible to reduce noise. Underwater, where lighting is limited, you might be tempted to increase the ISO. However, try not to exceed ISO 800. Use lights or flashes to compensate for low light instead.
  • Aperture: Aperture affects depth of field. For wide-angle shots, use a smaller aperture (higher f-number) to keep more of the scene in focus. For macro shots, you might want a larger aperture (lower f-number) to blur the background and make the subject stand out.
  • Shutter Speed: Faster shutter speeds are necessary to capture quick movements clearly, such as swimming fish. Aim for at least 1/125 second; for faster-moving subjects, you might need to go faster.

White Balance and Filters

  • White Balance: Adjusting the white balance is crucial as water filters out sunlight, especially red light, which can make everything look blue or green. If your camera allows manual white balance, adjust it according to the depth and water conditions. Some cameras offer an underwater setting that can be helpful.
  • Using Filters: Red filters can be used with available light (without a flash) to bring back some of the red tones lost underwater. They are most effective in sunny conditions at depths up to about 60 feet. For deeper dives, artificial lighting is usually necessary.

Using Flash and Artificial Lighting

  • Flash: A flash or strobe is essential for color correction and bringing out the vivid colors of the marine life, as it replaces the color lost with depth. It’s particularly crucial for close-up and macro photography.
  • Diffusers: When using a flash, a diffuser can help soften the light, which provides more even lighting and reduces harsh shadows and hot spots.

Final Tips

  • Test Your Settings: Before diving, take some test shots using a dive tank or at shallow depths to adjust your settings. What works on land might not work the same underwater.
  • Be Flexible and Patient: Underwater conditions can change rapidly. Be prepared to adjust your settings accordingly throughout your dive.
