Introduction
Underwater photography can be a thrilling and rewarding experience, offering a glimpse into the breathtaking beauty that lies beneath the waves. However, one of the biggest challenges that underwater photographers face is dealing with strong currents. These currents can make it difficult to maintain stability and effectively operate a bulky camera underwater. This is where a reef hook becomes an invaluable tool for underwater photographers, allowing them to navigate challenging currents and capture stunning images of current-ridden environments.
Section 1: What Is a Reef Hook?
In its simplest form, a reef hook is a curved metal rod that is attached to a line. This line is controlled by and/or mounted to a diver, providing stability in strong currents. Unlike a muck stick, which is a straight rod used for pointing out critters or stabilizing a diver during muck diving photography, a reef hook is specifically designed to assist photographers in challenging current conditions. Reef hooks come in a variety of sizes, ranging from 4 to 12 inches in length, and the length of the line can also vary, from just a couple of feet to several body lengths. Some reef hooks feature a line on a reel or are made of a sturdy long rope.
Section 2: When to Use a Reef Hook for Underwater Photography
The use of a reef hook is not necessary on every dive. It is most effective in destinations with strong currents, such as Galápagos, Cocos, and Fiji, where it may be required on every dive. Two conditions determine the ideal usage of a reef hook. Firstly, there should be a significant enough current that using the reef hook will result in stability. Insufficient current or inconsistent currents will prevent the line from becoming taut, rendering the reef hook ineffective. Secondly, the situation should require the photographer to remain in the same spot for an extended period. For example, during a drift dive, the current might be too strong to stop and take images until reaching a specific location with abundant current and subjects of interest.
Section 3: How to Use a Reef Hook
Using a reef hook effectively begins during dive preparation. Since reef hook lines can be long, it is important to avoid tangling. One method to prevent this is by using a “daisy chain” technique to condense the line until ready for use. Once the line is shortened, the reef hook can be stored in a pocket or attached to a D-ring clip on the diver’s BCD. It is recommended to attach the clip to a D-ring near the waist, rather than the chest, to maintain balance in strong currents. When the dive guide signals it’s time to hook in, the photographer can easily retrieve the hook from the pocket or clip and control the camera with one hand, while using the other to manage the line.
Finding an appropriate spot to hook in is crucial. Live coral should be avoided to prevent damage, and instead, sturdy rocks or dead coral can be used. It is important to ensure the stability of the chosen surface, as some dead coral can be brittle and rocky areas may shift. The length of the line can be adjusted based on the photographer’s preference. If possible, the line can be cut to a single body length (4-6 feet) before the dive. If this is not an option, the clip can be used to lock the daisy chain at the desired length.
Section 4: Tips for Underwater Photography with a Reef Hook
When utilizing a reef hook, certain adjustments and techniques can enhance the quality of underwater images. Here are the key tips to consider:
Use Short Strobe Arms:
In conditions where reef hooking is necessary, longer strobe arms can be challenging to maneuver in strong currents. Using shorter strobe arms, such as 8-inch arms instead of the typical 12-inch ones, reduces the risk of flailing and allows for more controlled lighting.
Choose a Longer Focal Length Lens:
Since reef hooking restricts mobility, it is advisable to use a longer focal length lens to compensate for being at the mercy of the current. This allows photographers to capture subjects from a distance, even when unable to approach them closely. Opting for a wide-angle rectilinear zoom lens instead of a fisheye lens can be a suitable choice.
Adjust Lighting Techniques:
When shooting in current-rich environments, photographers may find themselves further away from subjects than in other diving scenarios. This distance makes it more challenging to use strobe light effectively. To compensate, relying more on natural light by increasing ISO and opening up the aperture is recommended. This technique can also minimize the presence of backscatter, which is common in nutrient-rich currents.
Beware of Bubbles:
While reef hooking allows photographers to remain in a fixed position, bubbles from fellow divers can still drift with the current and interfere with the composition of images. To reduce the chances of bubbles obstructing shots, positioning oneself ahead or below the group can minimize their impact.
Practice Using the Reef Hook:
It is essential to get comfortable with using a reef hook before attempting to use it in challenging conditions. Practice taking the hook out, attaching it, and putting it away on dives with no current. Familiarize yourself with the length of the line and the process of hooking in. Once comfortable, gradually attempt reef hooking in moderate currents to gain experience and build confidence.
Safety First:
Using a reef hook during a dive requires a certain level of skill and experience. Diving in strong currents, even while using a hook, can be challenging. The hook can dislodge, potentially separating the diver from the group. In extreme cases, powerful currents can even flood or remove a diver’s mask. Prioritize safety at all times and be aware of potential risks while trying to capture stunning images.
Conclusion
A reef hook is an indispensable tool for underwater photographers venturing into environments with strong currents. By using a reef hook effectively, photographers can maintain stability and capture breathtaking images in challenging conditions. It is recommended to invest in a quality reef hook, as it can make a significant difference in the success of an underwater photography expedition. Remember, while using a reef hook provides opportunities for incredible shots, it is crucial to prioritize safety and adhere to responsible diving practices. With proper technique and preparation, underwater photography in current-ridden environments can yield truly remarkable results.
