Which Camera Should I Get for My Dive Trip?

Interested in underwater photography and wondering how to choose a camera for your scuba diving needs? We compare the PowerShot G7 X Mark III and a generic action camera to find out their main differences and help you make a more informed choice.

Get a rough idea of what the camera offers

There is no one camera that suits all. Understanding your needs will help you make a better decision when choosing a camera. Are you concerned with high image quality and resolution? Do you shoot more photos or videos? Will you dive at areas of a certain depth where flash is required to light up your surroundings? Consider these factors and then look for the camera that suits the requirements.

For example, a compact camera like the PowerShot G7 X Mark III has:

  • A 20-megapixel 1-inch type stacked image sensor: This is larger than the 1/2.3-inch type sensor on many action cameras and helps to capture better quality images even in conditions with little ambient light like what you get underwater. 
  • A native ISO speed of up to 12800: Offers more flexibility in low light conditions.
  • A convenient built-in flash: For better-lit images with minimal gear.
  • High-speed continuous shooting at up to 30 frames per second (RAW burst mode): To improve your chances of getting picture-perfect shots of fast-swimming sea creatures.
  • Up to 4K/30p cropless video recording: For taking high-resolution videos of your dives and the things you see around you.
  • Support for vertical videos: So you can directly capture videos in portrait orientation and share them on social media without having to first reorientate them in a third-party app.

 

For photography: Choose the camera that gives you more control

Look for features such as:

If your main purpose is to take photos underwater, you probably want more control over photo outcomes. That's the beauty of a camera like the PowerShot G7 X Mark III, which has full Manual as well as semi-automatic (Program, Aperture-priority, Shutter-priority) exposure modes, allowing you to adjust the shutter speed and/or aperture in addition to ISO speed and exposure compensation. In comparison, most generic action cameras only allow you to control the latter two settings.

That's not all. Canon's cameras have a Custom White Balance feature that helps to accurately compensate for the "blueness" of underwater scenes by using a reference shot. (Learn more about why custom white balance is important for underwater photography here.) You can also manually adjust the brightness of the built-in flash. RAW format recording is supported, allowing you to recover details from shadows and highlights or even adjust colours and tones by post-processing the RAW files in software like Canon's free Digital Photo Professional.

Here are some examples of effects to try with manual/semi-manual exposure settings:

Know which accessories to get

It really depends on what you are trying to shoot, and how serious are you in underwater photography to know which accessories you should be getting. An underwater housing protects your camera from getting wet; a strobe helps to light up your subject when it’s dark; and a diffuser softens the light from the flash to create a softer image. Sometimes it’s not about simply bringing your camera underwater and shooting away, but finding what kind of images you aim to capture, and honing your photography skills to achieve that (with accompanying accessories).
