Les meilleurs réglages, accessoires et astuces GoPro pour la plongée et le snorkeling sous l'eau


Is the GoPro Hero 9 Waterproof?

GoPros were essentially created for capturing surfing adventures from a POV perspective, making them highly suitable for water use.

The GoPro HERO 9 is waterproof without needing an additional waterproof housing, capable of withstanding depths up to 10 meters or 33 feet.

This makes it great for activities like swimming, snorkeling, exposure to rain, waterfalls, kayaking, and paddleboarding.

When Do You Need an Underwater Housing?

However, recreational scuba diving often exceeds these depths, increasing the pressure and the risk of water breaching the camera’s seals.

If you plan on Plongée sous-marine, it’s wise to encase the HERO 9 Black in an underwater housing, which is rated for depths up to 196 feet or 60 meters, far exceeding the limits of typical recreational diving.

How To Use Underwater Housing

It’s crucial to ensure that the camera’s side door is securely locked and that its rubber seals are clean and intact to prevent any gaps that might allow water ingress. Also, ensure that the lens cover is properly secured.

For the camera to remain waterproof, the side door must be completely closed, which means you cannot access the USB port for external power while underwater. 

Remember, the touchscreen doesn’t function underwater, although it can still serve as a viewing screen. Also, neither GPS nor WiFi will work underwater—this isn’t a flaw of the HERO9, but rather a limitation of the signals themselves.

Is GoPro Hero 9 Good for Underwater Photography?

Absolutely! The GoPro Hero 9 is a fantastic choice for underwater photography. It’s waterproof up to 33 feet (10 meters) on its own, which makes it perfect for snorkeling and swimming.

The Hero 9 captures sharp, vivid images and has features like Stabilisation HyperSmooth, which really comes in handy when you’re moving through the water. There are various modes and settings beneficial for underwater photography, including the ability to adjust ISO, shutter speed, and exposure.

This flexibility, combined with high-resolution video capabilities (up to 5K), makes it a robust choice for capturing high-quality underwater images and footage.

How To Set Up GoPro Hero 9 For Underwater Shooting

When the camera is sealed in the Dive Housing, access to the touchscreen is blocked, which restricts any setting adjustments other than changing the shooting mode.

To manage this, you’ll need to set up your camera before the camera is enclosed in the housing.

Filtre rouge

The primary challenge the GoPro HERO 9 encounters with underwater wide-angle video is its inability to set a manual white balance. Cameras need this capability to restore the red, orange, and yellow hues that are typically lost as you go deeper into water dominated by blue, green, and cyan tones.

By attaching a color correction filter to the GoPro HERO9, you can reintroduce these warm colors without needing to adjust the camera’s settings.

I recommend using the following filters:

  • Light Red Filter: Best for color correction in clear freshwater at shallow depths ranging from 2-15 feet.
  • Filtre rouge: Ideal for adjusting colors in blue or tropical waters at depths of 15-85 feet.
  • Filtre magenta: Optimal for correcting colors in greenish waters, such as those in lakes and reservoirs, at depths between 8-75 feet.

Can GoPro 9 Go in Salt Water?

GoPro Hero 9 cameras are suitable for use in both fresh and salt water.

photos sous-marines avec gopro

Toutefois, étant donné que les salt water can be highly corrosive, it’s crucial to take proper care of your equipment after exposure.

Each time you use your GoPro in salt water, make sure to thoroughly rinse the camera and any associated gear with fresh water afterward. This helps to remove any salt residue that could potentially damage the camera’s housing and internal components over time.

After rinsing, gently dry your GoPro with a soft, lint-free cloth to avoid water spots and to ensure no moisture remains on the camera.

It’s also beneficial to disassemble any removable parts like the battery and SD card to dry the compartments under them, as trapped moisture can lead to corrosion or mold.
