The D500 was housed in a Nauticam D500 housing and equipped with Subsee +5 and +10 diopters and a Nauticam flip adapter for added magnification. Lighting was provided by a Sola 2500 flood light and a Bluewater 1000 focus light. The D500’s cropped sensor and autofocus system make it perfect for capturing close-up details of small creatures and textures underwater.

Benefits of Using Both Cameras on One Dive Trip

Using both the D850 and D500 during the same trip allows photographers to switch quickly between wide-angle and macro photography without changing ports or lenses underwater. This flexibility is invaluable when encountering a diverse range of subjects in rapid succession. Both lenses used are AF-S lenses with internal autofocus motors, ensuring fast and reliable focusing performance, which is critical when capturing unpredictable marine behavior.

Autofocus and Camera Performance

The D850 delivers straight-out-of-camera images that are noticeably better in terms of brightness and low-light performance compared to earlier models like the D500 or D810. For wide-angle photography, the 3D tracking autofocus mode was employed on the D850, while the D500 used spot focus in continuous focus mode for macro shots. These settings help maintain sharp focus on moving subjects in challenging underwater environments.

Trip Overview: Exploring the Sea of Cortez

The dive trip took place aboard the Rocio Del Mar in early October 2018, traveling from San Jose del Cabo to Puerto Peñasco, covering roughly 600 nautical miles over 12 days. The Sea of Cortez is known for its rich biodiversity and offers a variety of encounters with both large and small marine life. The trip was somewhat affected by a hurricane forecast, but with adjustments to the itinerary, the crew ensured ample diving opportunities and diverse marine encounters.

Dive Experience and Marine Life Encounters

The day often began with an early pre-breakfast dive, taking advantage of the peaceful, uncrowded waters of the Sea of Cortez. Night dives revealed spectacular scenes such as hundreds of mobula rays feeding on plankton attracted to lights in shallow water. Dusk dives captured the heightened activity of hunting and mating fish, accompanied by swirling flocks of sea birds. Throughout the trip, encounters with playful sea lions, dolphins, and giant Pacific mantas provided exceptional photographic opportunities.

Lighting Techniques and Strobes for Underwater Photography

Lighting is one of the most critical factors in underwater photography. Water absorbs light and colors, especially reds and yellows, resulting in images that can appear blue or green and lacking contrast. To counteract this, underwater photographers rely heavily on strobes and continuous lights to restore color, detail, and sharpness.

For this trip in the Sea of Cortez, the YS-D3 LIGHTNING strobes played a vital role in illuminating subjects both wide and close-up. Using strobes effectively requires understanding light placement, power settings, and how light interacts with particles in the water.

Properly positioned strobes help bring out the vibrant colors of marine life and prevent backscatter, which is the reflection of light off suspended particles that create distracting spots in photos. Positioning strobes slightly off-axis and using diffusers softens the light, producing more pleasing results and better texture.

Wide Angle Lighting Challenges and Solutions

When shooting wide-angle images with the Nikon D850 and 16-35mm lens, lighting large subjects like manta rays or sharks poses unique challenges. These animals can move quickly and unpredictably, and the wide field of view requires strobes to illuminate a broad scene evenly without harsh shadows.

To achieve this, strobes are usually mounted on flexible arms, allowing the photographer to adjust the light angle dynamically. Using two strobes at roughly 45-degree angles helps create balanced lighting and reduces flatness. It’s essential to consider the distance from the subject, as light intensity decreases exponentially with distance underwater.

In environments like the Sea of Cortez, natural ambient light often supplements strobes during shallow dives. Early morning or late afternoon light provides a warm, directional quality that enhances the image depth. Combining natural light with strobes requires careful exposure balancing to avoid overexposing highlights or losing shadow detail.

Macro Lighting Techniques

Macro photography demands even more precise lighting control due to the proximity of the subject and the high level of detail captured. For macro shots with the Nikon D500 and 105mm lens, the use of a Sola 2500 flood light and Bluewater 1000 focus light provides constant illumination and assists autofocus in dim conditions.

The strobes are often used with diffusers and snoots to direct the beam narrowly onto the subject, highlighting textures and colors without illuminating unwanted areas. The proximity of the lights to the subject can create dramatic shadows, which can be creatively used to add depth but must be managed to avoid losing detail.

Using diopters (+5 and +10) extends the macro capability, allowing the capture of even smaller details. However, magnifying the subject also magnifies any lighting imperfections, so precise control over light direction and intensity becomes even more critical.

Camera Settings and Techniques for Underwater Shooting

Choosing the right camera settings is essential for achieving sharp, well-exposed underwater photos. Both the Nikon D850 and D500 offer full manual control, allowing photographers to adjust aperture, shutter speed, ISO, and focus modes according to conditions.

For wide-angle shots, aperture settings around f/7 to f/11 balance depth of field with sharpness. Shutter speeds between 1/125 to 1/250 seconds help freeze the motion of fast-moving subjects or water currents. ISO is kept low (ISO 200 to 640) to maintain image quality and reduce noise, especially in deeper or darker conditions.

In macro photography, apertures often range from f/16 to f/22 to maximize depth of field given the very close focusing distances. Faster shutter speeds are required to counteract camera shake or subject movement. ISO is similarly kept as low as possible while maintaining adequate exposure.

Autofocus mode is crucial underwater. For wide-angle, 3D tracking helps maintain focus on large, moving subjects. For macro, spot focus with continuous servo autofocus ensures sharp focus on small, precise points even when the subject moves slightly.

Handling and Buoyancy with Underwater Camera Equipment

Using large DSLR setups underwater requires mastering buoyancy and handling techniques to avoid disturbing marine life and to maintain stability for sharp images. The Nikon D850 and D500 setups, complete with housings, ports, and strobes, can be bulky and heavy.

Proper buoyancy control allows photographers to hover steadily without touching the reef or disturbing sediments, which can cloud the water. Using wrist straps or a camera tray system helps secure equipment and reduces fatigue.

Approaching subjects slowly and minimizing sudden movements increases the chances of capturing natural behavior and prevents scaring away shy creatures. For macro subjects, patience is key, as many animals will only reveal themselves after waiting quietly.

Environmental and Ethical Considerations in Underwater Photography

Respecting the underwater environment is paramount. The Sea of Cortez is a rich ecosystem, and photographers must take care not to damage fragile corals or disrupt animal behavior.

Avoid touching or chasing wildlife, and never remove anything from the environment. Using appropriate dive techniques to maintain distance and avoid contact with the substrate helps preserve the habitat.

Photographers also contribute to conservation by documenting marine life and sharing images that raise awareness of the ocean’s beauty and fragility.

Post-Processing Tips for Nikon D850 and D500 Images

After returning from a dive, post-processing is essential to bring out the best in underwater photos. Raw files from both the D850 and D500 retain rich detail and color information.

Basic adjustments include white balance correction to counteract the blue-green cast, exposure tweaking, and contrast enhancement. Noise reduction can help clean up higher ISO images without losing detail.

Sharpening and local contrast adjustments enhance texture, especially important for macro shots. Careful cropping can improve composition without losing resolution, given the high megapixel counts of both cameras.

Using software that supports tethered shooting and raw processing for Nikon files streamlines the workflow and allows fine control over image quality.

Adjusting shutter speed, aperture, and ISO manually enables the photographer to balance ambient light with strobe illumination. For example, slower shutter speeds can be used creatively to convey motion blur in schooling fish or swaying corals, while faster shutter speeds freeze motion for sharp images of fast-moving subjects.

The Nikon D500’s cropped sensor magnifies the subject, making careful manual focusing and exposure control essential, especially when shooting macro with high magnification diopters.

Focus Bracketing and Focus Stacking

Focus bracketing is a technique where multiple images are taken at different focus distances to increase the overall depth of field. While underwater housings typically do not support automated focus stacking, photographers can manually bracket focus and later merge images during post-processing.

This method is particularly useful in macro photography, where depth of field is shallow even at small apertures. Capturing multiple shots, focusing from the front to the back of the subject, allows for a final image that is sharp throughout, revealing intricate details otherwise lost.

The D850’s high-resolution sensor makes it ideal for this technique, as cropping and merging can be done without significant loss of quality.

Exposure Compensation and Histograms

Underwater scenes often confuse camera metering systems due to backscatter, reflective surfaces, and strong contrast. Learning to use exposure compensation and reading histograms is essential.

Using the histogram on the D850 or D500 helps ensure the image is properly exposed. Avoiding clipped highlights preserves detail in bright areas such as sunlit surfaces or reflective fish scales. Similarly, keeping shadows from going completely black retains texture in darker areas.

Manual adjustments to exposure compensation allow the photographer to fine-tune the balance between ambient light and strobe output, maintaining natural color and contrast.

White Balance Adjustments for Accurate Color

Water absorbs red wavelengths quickly, making underwater images tend to have a blue-green cast. While strobes restore some color, custom white balance settings improve color accuracy.

Both Nikon cameras allow manual white balance adjustments. Setting white balance underwater by pointing the camera at a white slate or neutral subject before shooting calibrates colors to the environment. This reduces the need for heavy color correction in post-processing.

Shooting in RAW format provides the greatest flexibility to tweak white balance during editing, allowing restoration of vibrant reds, oranges, and yellows.

Composition Techniques Underwater

Good composition is as important underwater as it is on land. Techniques such as the rule of thirds, leading lines, and framing enhance the visual impact of photos.

Wide-angle shots benefit from including foreground interest like corals or sea fans to add depth. Positioning animals off-center creates dynamic balance. Utilizing negative space emphasizes the subject’s size and movement in the vast ocean.

In macro photography, filling the frame with the subject eliminates distractions and highlights details. Backgrounds should be clean and uncluttered to prevent visual noise. Using natural elements like bubbles or soft light rays creatively adds atmosphere.

Handling Challenging Conditions: Currents and Visibility

The Sea of Cortez can present varying conditions, including strong currents and variable visibility. Photographers must adapt quickly to maintain image quality.

In strong currents, using faster shutter speeds prevents motion blur, and stabilizing with a weighted tray or holding onto fixed objects helps maintain steadiness. Positioning yourself up-current of subjects minimizes stirring up sediment.

When visibility is limited, shooting close to subjects reduces the water column between the lens and the subject, improving clarity. Using strobes at lower power settings reduces backscatter by minimizing light reflection off particles.

Utilizing Video Capabilities for Dynamic Storytelling

Both the Nikon D850 and D500 have strong video capabilities that complement still photography. Underwater videography captures movement and behavior that still images cannot.

Shooting 4K or Full HD video with manual exposure control and focus tracking allows capturing vibrant underwater scenes. Adding continuous lights like the Sola 2500 flood light enhances video quality by providing consistent illumination.

Combining stills and video offers a richer storytelling approach, especially for documenting marine life interactions or dive experiences.
