Optimal Subaquatic Configurations for Sony A7R II Digital Camera

The Sony a7R II, with its impressive features and capabilities, is a popular choice for underwater photography enthusiasts. To make the most of this camera underwater, it's essential to adjust some settings and understand its unique quirks.

Essential Camera Settings

The Sony a7R II offers several features that are particularly useful for underwater photography. Here are some key settings to optimize:

• White Balance: Assign this function to a custom button or the down button on the back of the camera for quick access.
• MF Assist: This option in the menu can be helpful for manual focusing.
• ISO AUTO Min SS: This feature allows you to specify a minimum shutter speed in Aperture priority mode.
• Peaking Level and Peaking Color: These options can help with manual focusing.

Changing Default Settings

Before diving, it's crucial to change some default settings in the camera menu. For instance, to turn off the automatic switch between EVF and LCD, go to Menu -> Settings (Cog Icon) -> Screen #4 -> Finder / Monitor -> Select either Viewfinder (Manual) or Monitor (Manual) -> OK to confirm.

Camera Control Customization

To split out the focus lock from the shutter release, assign the focus control to a custom button (C1 for Aquatica, AF/MF button for Nauticam) and remove the Autofocus from the Shutter Release.

Underwater Photography Best Practices

To capture stunning underwater images, consider the following tips:

• Use an underwater housing compatible with the Sony a7R II to protect your camera and allow full operation underwater. Brands like Nauticam or Ikelite offer robust options specifically designed for your model.
• Lens choice: Use wide-angle or macro lenses suitable for underwater scenes. For wide shots, a wide-angle lens allows close approaches to subjects, helping reduce water distortion and color loss.
• Camera settings:
• Set a wide aperture (low f-stop number) to let in more light, essential underwater where light is diminished.
• Adjust shutter speed to be relatively fast to avoid motion blur but not too fast to underexpose—around 1/125 to 1/250 seconds is typical depending on movement and lighting.
• Increase ISO gradually to compensate for low light, balancing exposure with minimal noise.
• Experiment with custom white balance to correct underwater color shifts (especially blues and greens) and achieve natural colors.
• Shoot in RAW format to preserve maximum detail and allow color correction in post-processing.
• Lighting: Use external underwater strobes or continuous lights to illuminate subjects and restore color lost with depth. Position lights carefully to avoid backscatter from particles.
• Focus: Use autofocus modes suitable for underwater contrast situations, or manual focus if required.
• Practice buoyancy control: Maintain stable positioning to prevent stirring sediment, which can reduce visibility and photo quality.
• Prepare memory: Use fast, high-capacity memory cards (e.g., Lexar CFexpress cards) to handle large RAW files and high burst shooting if doing action or wildlife photography.
• Practice operating your camera inside the housing before the dive—knowing your camera controls by feel is crucial underwater.

While this advice focuses on the a7R II, newer models like the a7R V have been used successfully underwater with advanced housings and gear, which might offer workflow and image quality improvements.

Video Settings

For HD video, the recommended settings are XAVC S HD, 30p or 60p, and manual control for shutter speed, aperture, and ISO.

In summary, mount your Sony a7R II in a high-quality underwater housing, use wide aperture, careful shutter speed and ISO settings, shoot RAW, customize white balance, add external lighting, and maintain good buoyancy for optimal underwater photography. Practicing these settings and handling will lead to the best results.

1. To excel in underwater photography with the Sony a7R II, take advantage of its customization options for better control, like assigning MF Assist, White Balance, and Peaking Level to easily accessible buttons.
2. Adjusting the ISO AUTO Min SS feature can help create optimal shutter speeds in Aperture priority mode for underwater photography.
3. Before diving, modify some default settings in the camera menu, such as turning off the automatic switch between EVF and LCD for smoother operation underwater.
4. Employing wide-angle or macro lenses suited for underwater scenes can lead to more captivating underwater images.
5. To achieve vibrant colors and brightness underwater, utilize external underwater strobes or continuous lights for proper illumination.
6. Strobe positioning is crucial to avoid backscatter, causing scattered debris to appears as bright specks, harming image quality.
7. In manual focus situations, reassign focus control to a custom button and remove Autofocus from the Shutter Release for improved control.
8. Reworking composition in underwater photography can elevate your images, focusing on the rule of thirds, leading lines, and framing whenever possible.
9. Categorize your captures using taxonomy tags or keywords in your image management system for efficient organization and future reference.
10. To showcase your best underwater photographs, enter them in open underwater photography contests, demonstrating your skills and knowledge in this specialized field, and winning prizes or industry recognition.
