Get Into the Blue With GoPro Underwater Digital Cameras

When you are near the water and want to take pictures, you may be considering what device you can use while taking shooting in low light or an action camera with video lights. Digital cameras specifically designed for underwater use can take pictures and underwater video. GoPro is a company that makes several versions of waterproof products.

How do waterproof digital cameras work?

The camera components of a waterproof camera are similar to those on a regular camera. A digital camera has an aperture and viewfinder. The viewfinder can be optical or electronic, and many products have both. When you shoot pictures, the aperture opens and light enters through the lens. A light detector inside the camera, either a charge-coupled device or a complementary metal-oxide-semiconductor (CMOS) image sensor, captures the incoming information and translates the light signals into electrical ones. What you would think of as an image turns into millions of digital pixels. When you view your footage, those pixels are combined to form images.

The area where they differ from traditional cameras is that certain components in an underwater camera are contained in a special housing. That housing is completely airtight so that water cannot get through and mix with internal parts.

What are some features to consider?

The housing is what makes a camera able to be submerged under water. Some models are encased in a housing that cannot be taken off whereas others come with a removable housing. For underwater cameras with a removable housing, rubber seals are used to keep water out when the housing is shut.

As you go deeper into the water, the pressure increases. In general, the thicker the glass that makes up the lens, the deeper the water presser it will be able to withstand. Underwater cameras may come with a depth rating so that you can know beforehand how far you can go. See the manufacturer site for details.

What are models that are waterproof without an external housing?

There are several units that can go underwater without any additional components. A few examples are:

  • FUSION: When all the doors/ports are closed, it can go down to five meters. It can take spherical video and photos so that you can have a 360-degree experience.
  • HERO6 Black: When the doors are closed, this model can go down to 10 meters. An optional housing can be used if you wish to go down to 60 meters. It uses a GP1 chip and can be zoomed in by touching the screen.
  • HERO+ LCD: This model can safely be submerged to 40 meters. It has built-in Wi-Fi and Bluetooth capabilities and has different light settings.
  • HERO+: With its non-removable housing, this one can go down to 40 meters. The model can record 1080p60 and 720p60 video and can capture 8 MP photos.
