How to Set Up Your Camera Settings for Underwater Photography

Listen Later

Ever taken your camera underwater only to end up with a memory card full of blue, blurry disappointments? You're not alone. In this episode, Camila Reyes breaks down exactly how to configure your camera settings for underwater photography, sharing the hard-won lessons from her own trial-and-error journey shooting Caribbean reefs and marine life. Whether you're prepping for your first underwater photo dive or feeling overwhelmed by all the dials and menus, this beginner-friendly guide walks you through shooting modes, aperture, shutter speed, ISO, white balance, and focus—so you can spend less time troubleshooting and more time capturing stunning images.

  • Full auto mode doesn't work underwater—water absorbs light and color in ways your camera's automatic calculations can't handle, which is why Aperture Priority or Manual mode produces dramatically better results.
    • Start with f/8 as your baseline aperture setting; it's forgiving across most underwater scenarios, works well with strobes, and keeps reef scenes and fish portraits sharp without sacrificing too much light.
      • A shutter speed of 1/125th of a second is a reliable starting point for freezing fish movement and compensating for camera shake, though faster subjects like sharks or schooling jacks may require 1/160th or higher.
        • Prepare your settings topside before descending, test with a few shots in shallow water, and expect to refine your configuration over your first several dives as you learn your local conditions.
          • Good buoyancy control matters more than perfect settings—if you can't hold still underwater, even the best camera configuration won't save your shots.
            • Keep a slate with your go-to settings written down; having a checklist mindset helps you stay consistent and troubleshoot quickly when conditions change mid-dive.
