Advanced Lighting Techniques with the YS-D3 and G9X Mark II
Achieving professional-quality underwater photos depends heavily on mastering lighting techniques. The YS-D3 Lightning Strobe offers the tools necessary for advanced lighting strategies, and when combined with the G9X Mark II, it opens a world of creative possibilities. One fundamental technique is strobe positioning. Positioning the strobe away from the camera lens and slightly to the side helps reduce backscatter and produces more natural lighting. By angling the strobe outward, photographers can achieve side-lighting that reveals texture and shape, particularly useful for photographing corals, fish scales, and the contours of underwater terrain.
In wide-angle photography, dual strobes are commonly used to evenly light larger scenes. When paired, two YS-D3 strobes provide broad, balanced coverage with minimal shadowing. The G9X Mark II’s wide-angle lens benefits from this setup by capturing vibrant, full-frame exposures. Placing the strobes at ten and two o’clock positions, slightly above the camera, ensures even distribution of light across the foreground and background. Adjusting the power levels independently can also help control the exposure balance between the two sides of the frame.
For macro photography, a single YS-D3 can suffice when carefully positioned. Lowering the strobe power and bringing the light closer to the subject reduces harshness and prevents overexposure. Using a snoot accessory helps focus the beam, allowing pinpoint lighting for small subjects like nudibranchs, shrimp, or pygmy seahorses. This technique isolates the subject from the background and adds drama to the composition by creating contrast between light and shadow. When using snoots, pre-visualizing the light path is essential. The YS-D3's focus light can assist in this process by previewing where the beam will land before the strobe fires.
Another powerful technique is backlighting, where the strobe is placed behind the subject and aimed toward the camera. This setup creates a rim of light around the subject, ideal for translucent marine life such as jellyfish or sea slugs. Backlighting adds a sense of depth and highlights the outline of the subject against a darker background. Because the G9X Mark II can be triggered with precision, photographers can time their backlit shots to align with subject movement, creating dynamic and artistic results.
Balancing ambient light with strobe light is another challenge that the G9X Mark II and YS-D3 can tackle effectively. In situations where ambient light is strong, such as in shallow reefs or clear waters, setting the camera to a slower shutter speed and a lower ISO allows for capturing background colors while using the strobe to light the foreground subject. This dual-lighting approach prevents the background from turning black, a common issue in strobe-dominated exposures.
Color correction is also an important element of underwater lighting. As water depth increases, red and yellow hues diminish. Using a strobe restores these colors, but color temperature adjustments may still be necessary. The YS-D3 provides accessories like warm diffusers that add warmth to the light and help replicate the appearance of natural sunlight. Setting the camera’s white balance to daylight or custom Kelvin values around 5000–5500K can further harmonize strobe and ambient light.

Maximizing the potential of the G9X Mark II and YS-D3 combination requires understanding not just the technical tools but also creative strategies. Achieving sharp focus underwater can be difficult due to low contrast, moving subjects, and limited light. The G9X Mark II's touchscreen makes selecting focus points easy, but pre-focusing on high-contrast areas and using focus lock can help in difficult situations. The camera’s face detection and tracking features also assist with moving subjects, although manual focus remains the most precise method for macro photography.
In macro work, using the camera’s closest focusing distance and composing carefully can produce frame-filling images of tiny creatures. Using a macro wet lens allows for even closer focusing and higher magnification. For composition, placing the subject off-center using the rule of thirds often results in more dynamic images. Keeping the background clean and minimizing clutter ensures the subject stands out, while using the strobe’s directional lighting adds depth.
In wide-angle scenarios, capturing the interplay between subject and environment is key. Including divers, coral, or schools of fish provides scale and context. Shooting upward toward the surface brings in natural light rays and creates a more dramatic atmosphere. Using a wide-angle dome lens allows the camera to get closer to the subject while still including background elements, which is essential for sharp and vibrant images.
Maintaining proper exposure is critical. The G9X Mark II provides exposure compensation, histogram display, and RAW capture for post-processing flexibility. Shooting in RAW allows for better recovery of highlights and shadows, especially in high-contrast scenes. Photographers should regularly check their images for exposure accuracy and adjust ISO, shutter speed, and aperture accordingly.
One often overlooked aspect of underwater photography is the background. A distracting or overly bright background can ruin an otherwise excellent photo. Controlling background exposure through careful strobe positioning and camera settings is essential. In dark or murky waters, using the strobe to light the subject while allowing the background to fade naturally can result in a clean, professional image. In clear water, balancing light between subject and environment produces more immersive compositions.
Safety is also an integral part of image capture. Photographers must ensure they maintain buoyancy control and awareness of their surroundings. Getting the perfect shot should never come at the expense of disturbing marine life or damaging the reef. Practicing good diving habits ensures both the safety of the environment and the longevity of the photographer’s gear.
