GoPro Hero 8 Black Underwater: Initial Thoughts & Review

A first look at the GoPro 8’s underwater performance including hypersmooth image stabilization, new mod capabilities, improved HDR photos, and 4K video @ 60p
By Nirupam Nigam

It’s probably safe to say that the GoPro HERO 8 Black is the top GoPro action camera for underwater photo and video. Somehow GoPro manages to release a new and improved product every year for the same low price of $399.99. In fact, autumn is turning out to be the unofficial GoPro season. 

Although the wild rumors of high frame rates and magical features that have been circling the internet for the past few months didn’t quite turn out, the GoPro 8 is looking like a solid upgrade from the GoPro 7. In fact, there are enough new features for scuba divers and snorkelers, that it might even make sense to upgrade. Particularly, HyperSmooth image stabilization 2.0, TimeWarp 2.0 and improved HDR photography with the option for RAW files are all exciting features for underwater creatives.

The GoPro line of action camera is undoubtedly the most popular underwater camera used both by enthusiasts and industry professionals. The GoPro HERO 8’s release is only going to help solidify its status as the universal camera for capturing action, whether it’s above or below the oceans we all love.

GoPro 8 Key Features

Hypersmooth Image Stabilization 2.0

Like with the GoPro HERO 7 Black, hypersmooth image stabilization is by far the most exciting feature, especially for underwater photographers and videographers. Smooth, unshaky video is essential for people operating their cameras in 3D underwater environments. Hypersmooth stabilization has been updated to be more powerful, as well as to have multiple levels of stabilization. It also includes a feature called Boost which allows you to level the horizon in-app.

Here is a sample of Hypermooth Image Stabilization from the GoPro HERO 7:


TimeWarp 2.0

 TimeWarp was another popular feature that was debuted with the GoPro HERO 7. It allows you to take smooth, hand-held timelapse video while moving around. TImeWarp 2.0 includes an automatic speed selection for even more creative effects. We can't wait to take the GoPro HERO 8 underwater to see just how well this feature could work. 


Improved Photo Mode

The GoPro HERO 8 features improved photos with better HDR. Moreover, you can now capture photos with RAW files. This will be a big deal for underwater photographers who intend to adjust whitebalance in post processing. JPEGs are difficult to edit and it's often impossible to fully recover underwater colors. RAW files are easier to edit and adjust white balance and exposure. Photos with the GoPro can now be edited from being washed out and blue to nice and colorful (to the limitations of the photo). Since the lack of RAW image format was one of the biggest things holding back using previous GoPro models for underwater photography, this could be a real game changer!


Live Burst Mode

Live burst photo mode is a new function to help you capture the perfect photo of the exact peak of the action moment. In Live Burst mode, when you hit the record button, it will capture the 1.5 seconds prior to pressing the button, as well as the 1.5 seconds after, at 30 frames per second (ie 90 frames in total). It also lets you use the photos as a 3 second 4k video clip.

This means if you are, for example, photographing a sea lion, and you see it blowing bubbles, as long as you hit the shutter within 1.5 seconds of seeing the bubbles, it will capture that moment the sea lion started blowing the bubbles. Very cool!

Design & Dimensions

The GoPro 8 (W: 66.3 mm; H: 48.6 mm; D: 28.3 mm) is a bit longer, a bit taller and a bit thinner than the GoPro 7 Black (W: 62.3 mm; H: 44.9 mm D: 33 mm). Overall they both take up the same amount of volume. Additionally, a change has been made with the lens cover design. Rather than the removable lens cover of the GoPro 7, the GoPro 8 has a built-in lens cover which cannot be removed. This means you have to be more careful protecting the lens cover, as it cannot be replaced. 

One other design change is around how the GoPro mounting works on land. There are now two folding mounting rings built-in to the bottom of the GoPro body, which means there's no need to use the "cage" for any topside GoPro mounting.

Dive Housing & Filter Use

Since the dimensions and the lens cover design have changed, this means the GoPro 8 has a new dive housing design, and the old super suit for the previous GoPro models cannot be used with the 8. Although not ideal for people with old housings, the advantage of this setup is that you don't have to mess around with taking off and putting on the lens cover every time you want to take your GoPro underwater. 

It remains to be seen whether old GoPro filters and flip systems will fit onto the new housing. Stay tuned for more info on this once we get the new dive housing to test things out.

Battery Compatibility

You can use old GoPro 7 batteries with the GoPro 8, and GoPro 8 batteries will work with older GoPro models.

Mods for Topside

Some of the most interesting developments for the GoPro 8 are clearly aimed at vloggers. GoPro has designed three "mods" which can be added to the GoPro: 

  • Media mod: Get premium shotgun-mic performance, 3.5mm mic and HDMI-out ports, and two cold-shoe mounts—all in one.
  • Display mod: A flip-up screen for framing your shots—so you can vlog like you mean it.
  • Light mod: Get powerful LED lighting for HERO8 Black, attach it to a GoPro mount or use it alone.

Yes, it would be great to have the LED lighting underwater, but it requires the media mod to use it, and the media mod is not waterproof. You can see what  the mods look like on the GoPro site.

Recommended GoPro HERO 8 Settings

Since the resolution and framerate options are the same as for the GoPro 7, we continue to recommend shooting in 2.7K at 60 fps, wide field of view, with hypersmooth image stabilization on. However, if you want the very best resolution, and more importantly have a computer which can handle 4K video (both processing power and hard drive space), then shooting at 4K/60 fps with hypersmooth stabilization is an excellent choice, and will give you more options for editing.

Once we see what options there are for changing modes, this recommendation may change for shooting macro video. 


GoPro HERO 8 Black Sample Video

The GoPro 8 black is not yet available to us to take underwater. As soon as it is out, we plan on taking some awesome video! Until then, here is a great sample video from the GoPro HERO 7. Footage from the 8 should look similar, except with even more image stabilization!



GoPro HERO 8 Recommended Accessories

GoPro 8 Protective Housing

As mentioned above, with new dimensions and the non-removable lens cover, the GoPro 8 requires a new underwater housing. Old GoPro underwater casings will not fit. The GoPro 8 is waterproof to 10 m/33 ft, so for any dive use you will want this underwater casing (which is rated down to 60 m, well beyond recreational depths). 


SeaLife Aquapod

SeaLife Aquapod

Capture your best selfie yet with the extendable Aquapod. Made by SeaLife, the Aquapod is designed for underwater use. Not only can you capture that selfie, but you can get the camera closer to your subject, whether it is something small or something skittish that you can't approach. The aquapod can also be quite useful for immersing the GoPro into the water from a small boat.

GoPro Multigrip Handle

GoPro Multigrip Handle

Adding a handle like the Beneath the Surface Multigrip handle adds stability and is an easy way to hold your GoPro while diving, or any other activity. Often, if handholding your GoPro, you'll see your fingers wrap around into the picture. This problem is solved with the handle.

GoPro Tray and Handles

GoPro Handles and Tray

Attaching your GoPro 8 to a tray and handles will make the camera easier to hold on to and much, much more stable underwater. In addition, the handles serve as a mounting point for video lights. Below are a few of our favorities:

Video Lights

i-torch fishlite video light

Bring color back into the picture with the use of video lights. Even a high-powered light will only illuminate a subject a few feet in front of you, so these are most useful for macro and close focus wide-angle video. Adding a video light to your GoPro setup will allow you to shoot professional-quality video on your next dive! Below are a few of our favorites:

MacroMate Mini GoPro 7 Flip Diopter Close-up Lens

Note: We are not sure yet if GoPro filters for the 7 will fit on the 8. Stay tuned for more information. If they do not fit, then we expect a Flip8 to be released sometime soon.

When attached with the Flip7 one-filter setup or Flip7 two-filter setup, the MacroMate Mini +15 flip diopter allows for your GoPro to take some striking underwater macro footage. Getting close really adds personality, color and detail to many of the smaller-sized critters on the reef. This diopter allows you to get only a few inches from your subject, perfect for golfball to baseball-sized subjects! Check out our Go Pro macro tutorial for more information.

For underwater photo and video, the GoPro HERO 8 Black has some excellent improvements over the GoPro HERO 7 Black. In particular, HyperSmooth image stabilization 2.0 and Timewarp 2.0 will be very useful features. However, the video resolution, photo resolution, and frame rates are the same as the GoPro HERO 7. It's likely that there will not be very many differences in image and video quality underwater. If you are a big fan of GoPro or shooting any model less than the HERO 7, this is probably going to be a great upgrade.

If you do have one of those older models (ie the 6 or prior), you can also consider upgrading to the GoPro 7, which is now going for a discounted price. Check out our detailed review here.

Many of the updates to the GoPro 8 are for topside use, mostly for vlog use. Those alone may be a good reason to upgrade, if that happens to be something you are interested in.
