It’s worth noting that these specialized housings may be more expensive due to their advanced features and construction. Assess your specific diving needs and budget to determine the appropriate housing for your underwater photography adventures.

The primary function of the housing is to keep water out and protect your camera. This is achieved through a simple o-ring and clamp seal system. Before each use, it’s important to clean and lubricate the seal to ensure its effectiveness.

Some advanced housings may feature vacuum ports for testing the seal and warning systems to alert you if the seal fails, providing an added layer of protection.

The housing also includes waterproof buttons and knobs that allow you to control your camera’s functions. Each of these controls has its own o-ring seal, which can be sensitive to dirt and particles. To prevent damage, it’s essential to thoroughly clean the housing with fresh water after each use.

Remember to carefully follow the housing manufacturer’s proper use and maintenance instructions. Neglecting these procedures can potentially jeopardize the safety of your camera and lens.

Strobes or Lights

Underwater strobes or video lights are essential for illuminating subjects and restoring colors that are lost underwater. While natural light is an option, there are three main lighting choices to enhance your underwater photos: the camera’s built-in flash, a strobe, or underwater lights.

When starting out, you can rely on the built-in camera flash. However, keep in mind that its reach is limited underwater, making it suitable mainly for close-up shots of small subjects.

Using a strobe or video light is recommended to expand your creative possibilities. Strobes are more powerful than built-in flashes, allowing you to capture larger subjects and those located at a greater distance. However, it’s important to note that you won’t see the exact lighting effect with strobes before taking the photo.

Alternatively, underwater video lights provide constant illumination, allowing you to preview the lighting effect through the camera’s viewfinder before capturing the shot. These lights can be turned on and off as needed.

When considering additional lighting for your camera rig, starting with a single strobe and a small focus/video light is a practical choice. This setup will enable you to capture high-quality images of various underwater subjects.

Lenses

Wide-angle and macro lenses are commonly used in underwater photography. Wide-angle lenses capture expansive seascapes and allow you to get close to large subjects, while macro lenses capture intricate details of smaller marine life.

The choice of lenses can greatly impact the versatility and creativity of your underwater photography. In underwater photography, wide-angle and macro lenses are commonly used. Different lenses are available for various shots, and compatibility depends on your camera type and model. Here are a couple of examples:

  • Macro lens – A macro lens is ideal for capturing intricate details of small, close-up subjects underwater. It lets you focus on tiny marine life and reveal its intricate textures and patterns.
  • Wide-angle lens with dome port – A wide-angle lens with a dome port can create a fish-eye effect, expanding your field of view and capturing the vastness of the underwater environment. This is particularly useful for landscape shots or capturing larger marine creatures.

Before purchasing lenses, it’s crucial to ensure compatibility with your housing. Check that your housing supports the specific lenses you intend to use. This ensures a proper fit and allows you to take full advantage of the lens capabilities while keeping your camera safe underwater.

Buoyancy Control Devices

Buoyancy control devices, such as buoyancy control arms or floats, help achieve neutral buoyancy while diving with your camera setup. These aids make it easier to maneuver and stabilize your equipment underwater.

Underwater Photography Tips and Techniques

Underwater Photography Tips and Techniques

Underwater photography can differ slightly from land photography, so you will need some helpful tips and tricks. To capture amazing photos under the surface, practice these tips and techniques:

Practice composition techniques

Composition underwater follows similar principles to above-water photography, but the unique underwater lighting opens up new creative possibilities. The presence of sunlight filtering through the water can add a captivating element to your shots. While strobes are important, consider incorporating other light sources, like sunlight from above, into your composition. Silhouettes and light rays can create stunning effects.

Even underwater, don’t neglect the tried-and-true composition techniques like the Rule of Thirds or the Golden Ratio. These principles still play a significant role in determining the success of your images, regardless of the subject matter. So, remember to apply them to create visually compelling compositions.

Master your equipment before the dive

Make the most of every opportunity to practice, even if it may seem silly at first. Take short swims near the beach or have fun sessions in the pool to train yourself. This allows you to not only become familiar with your camera equipment but also practice setting it up and keeping it clean. The more you use your gear, the more comfortable you’ll become with it. When it comes to choosing the right camera for underwater photography, it’s an important decision. There are dedicated cameras specifically designed for underwater use, and you can find a helpful guide for selecting the best underwater cameras.

Many divers don’t have their own boats, so they often rely on scheduled trips with limited time. It’s crucial not to waste valuable dive opportunities by being unfamiliar with your equipment. Ensure you are well-prepared and knowledgeable to maximize your underwater adventures.

Use natural light to your advantage

When taking photos underwater, it’s best to shoot during the golden hours (early morning or late afternoon) because it’s when the sunlight creates a warm and vibrant ambiance. Experiment with different angles to capture stunning light rays and silhouettes.

External strobes are great for capturing great underwater images but don’t limit yourself to just using flashes. Get creative by incorporating the beautiful backlighting from the water’s surface into your shots. This not only uniquely frames your subjects but also adds depth and visual interest to your composition. Don’t overlook the power of natural light in your underwater photography. Take advantage of bright objects, such as reflective sand areas, which can serve as additional light sources in your photos.

Know the sun’s direction

Be aware of the sun’s direction when shooting underwater, as it greatly impacts the lighting and shadows on your subject. Unlike on land, it may not be immediately apparent underwater. Shooting towards the sun can result in backscatter caused by particles in the water, reducing contrast. Shooting slightly toward its angle can still create this issue even when the sun appears directly overhead. Position yourself with the sun behind you to capture natural-light photos with optimal clarity.

However, there are instances where shooting towards the sun can create interesting silhouettes and backscatter, adding a moody atmosphere to your images. These exceptions can be creatively appealing, but you need to be aware of the sun’s direction to take advantage of them. Remember, understanding the direction of the sun is crucial in underwater photography.

Understand how light behaves underwater

Light behaves differently underwater compared to on land due to various factors such as absorption, scattering, and reflection. Understanding how light behaves in water is crucial for capturing great underwater photographs.

  • Absorption: Water absorbs light at different wavelengths, and as you descend deeper, certain colors are absorbed more rapidly than others. Red light is absorbed first, followed by orange, yellow, and so on. This phenomenon is known as color loss, and it means that the deeper you go, the less vibrant and colorful your images will appear.
  • Scattering: Scattering occurs when light rays change direction as they interact with particles or molecules in the water. It leads to a loss of contrast, sharpness, and overall clarity in your photos. Tiny suspended particles, such as plankton or sediment, can cause scattering and reduce visibility underwater.
  • Reflection: Light can also reflect off various surfaces underwater, including the water’s surface itself, the sea floor, corals, and other objects. Reflections can create unwanted glare or highlight certain areas, affecting your photos’ overall exposure and composition.
  • Direction and Intensity: The direction and intensity of light play a significant role in underwater photography. Depending on the angle of the sun or artificial light sources, you can achieve different effects and highlight specific details. Controlling the direction and intensity of light can help create more dynamic and visually appealing underwater images.

These are why many underwater photos look dark, blue, and low in contrast. Photographers often use artificial lighting sources such as strobes or video lights to overcome these challenges. These help restore color, enhance contrast, and provide sufficient illumination to capture detailed and well-exposed photographs.

Shoot up and get close to your subject

The great thing about being underwater is that you can be free to move and take photos from any angle. Use that to your advantage when doing underwater photography. Shooting from the surface or shooting down is often easier, but it makes boring photographs. There’s less contrast, and it doesn’t captivate the beauty of your subject. Even in just a few feet of water, diving down means you can capture your shots horizontally, revealing more contrast and a captivating background. Consider shooting your subject at a slight upward angle – it gives a more visually appealing perspective of the subject and creates a striking contrast with the background, drawing attention to your focal point.

To enhance the visual impact of your photos, aim to get as close to your subject as possible. Underwater photography thrives on minimizing distance, preserving contrast, and vivid colors. This is why many photographers use ultra-wide lenses, including fish-eye lenses, to maximize their subjects’ proximity.

Focus on the eyes

When capturing underwater images, ensuring your subject is in focus is crucial. But where should you focus? In most cases, especially in wildlife photography, it’s best to prioritize the eyes. Even if other parts of the subject may be out of focus, keeping the eyes sharp establishes a connection between the viewer and the subject, making the overall image more captivating. Remember, focusing on the eyes creates a powerful bond that draws the viewer in.

Adjust white balance manually

Consider trying manual white balance adjustment for your underwater photography. When you set the white balance on your camera, you’re essentially telling it the expected color temperature of your photo. If you’re using a strobe or internal flash to illuminate a close subject, you can leave the white balance on Auto, as it adjusts to the flash’s color temperature. However, if you’re shooting in ambient light without artificial lighting, setting the white balance manually is recommended. Access your camera’s menu, navigate to the manual white balance setting, and capture a photo of a white dive slate. This helps restore the colors, especially in shallow water. Remember that manual white balance’s impact becomes less noticeable beyond 10 meters (30 feet) depth.

Adjust camera settings when changing directions

When shooting underwater, the direction you point your camera can affect your exposure settings. Shooting downwards, horizontally, or upwards requires different adjustments to get the right exposure. To handle these changes, try using aperture priority mode. This mode allows your camera to automatically adjust the settings based on your shooting direction, ensuring proper exposure. Another helpful feature is the Auto ISO setting. You can set a minimum shutter speed, like 1/200 second, and let the camera adjust the ISO as needed. This combination of aperture priority mode and Auto ISO gives you control over the aperture and shutter speed while adapting to different shooting directions.

Do not scare your subject

Avoid scaring your underwater subjects if you want to capture great photos. Chasing them will only result in missed opportunities and unflattering shots.

Instead, stay calm and minimize your movements. By being peaceful and non-threatening, you can gain the trust of the animals and capture better images. Remember, they have chosen their location for a reason and are unlikely to swim away if you maintain a steady presence.

If you’re snorkeling, practice diving down while holding your breath. This allows you to maximize your encounters with marine life. Stay still to conserve oxygen, and consider practicing in a pool if needed.

Equalizing the pressure in your ears is also essential for comfortable diving, whether snorkeling or scuba diving. Pinch your nose and gently exhale through it to release the pressure. This technique ensures a more enjoyable experience and prevents unnecessary flailing that might scare away your subjects.

Prevent fogging

Prevent fogging in your underwater photography gear to avoid ruining your photos. Fogging happens when water condenses inside the housing or lens, often caused by trapped humidity and temperature differences.

For underwater housings, use a desiccant pack to absorb moisture. Ensure the desiccant is new or dehydrated, as saturated ones won’t work. Alternatively, you can use tampon fluff as a makeshift option, but be careful not to let fibers or packs get caught in the seal.

If you’re using a GoPro or waterproof camera without extra housing, reducing the risk of fogging is still possible. Close the housing, including battery and charging ports, in a dry, air-conditioned space whenever possible. When changing batteries in a humid environment, ensure your hands are completely dry and prevent any droplets from entering the seal.

Avoid exposing the camera to direct sunlight or excessive heat, as this increases the likelihood of fogging.

Learn about the marine environment and respect it

Gaining knowledge about the marine environment is valuable for underwater photography. It keeps you safe by understanding potential dangers to avoid and helps you capture better shots.

Learning about marine life makes you familiar with their behaviors, enabling you to anticipate and photograph them effectively. Also, underwater photography often brings out vibrant colors that may appear differently in your photos than what you see with your eyes. Understanding the true colors present and how to incorporate them into your compositions can greatly enhance your underwater images.

Sometimes, it’s easy to get a bit overzealous when you see a subject you really want to photograph. But always remember that you’re just a guest, and as a guest in their environment, treating marine life with care should be a top priority.

Avoid the temptation to disturb or manipulate marine creatures for better photos. It’s unethical, dishonest, and can harm the animals. Instead, approach them calmly and capture your shots without causing any disturbance. Afterward, give the animals space to go about their natural activities.

Furthermore, be mindful of your equipment. Keep all hoses secured and avoid any dangling items that could potentially damage the delicate reef ecosystem. Practicing these considerations allows you to photograph underwater subjects while preserving the marine environment.

Conclusion

Learning and trying out underwater photography is an extremely rewarding activity. It may require lots of practice and specialized equipment, but it’s worth the effort for divers who like to share what they see below the surface. Underwater images bring us awareness of marine life and remind us of the interconnectedness of the planet.
