Using a GoPro camera or a Smartphone camera with a dome port can help you capture stunning underwater photos and videos with minimal distortion. Here are some tips for using a GoPro camera with a dome port:

1. Choose the right dome port: GoPro cameras are compatible with a wide range of dome ports, but it’s important to choose one that is specifically designed for your camera model. Check the manufacturer’s specifications to ensure that the dome port is compatible and fits securely onto your camera housing.
2. Adjust your settings: Before you start shooting, make sure to adjust your camera settings to suit your shooting environment. Consider factors such as the water temperature, lighting conditions, and the type of subjects you will be shooting.
3. Keep the dome port clean: The dome port can easily get dirty or smudged underwater, which can affect the quality of your photos. Make sure to clean it regularly with a soft cloth or sponge to keep it free from debris and smudges.
4. Avoid touching the dome port: When you’re shooting with the dome port, it’s important to avoid touching the surface of the dome as much as possible. This can cause smudges or scratches, which can affect the quality of your photos.
5. Shoot from different angles: Experiment with shooting from different angles and distances to capture a variety of perspectives. Try shooting from below your subject or from different sides to capture interesting and dynamic shots.
6. Practice makes perfect: Using a dome port takes some practice, so don’t be discouraged if your first few shots don’t turn out as you’d hoped. Keep experimenting with different settings, angles, and subjects to find what works best for you.

By following these tips, you can use your GoPro camera or SmartPhone camera with a dome port to capture stunning underwater photos and videos with minimal distortion.
