Underwater Video: 10 Considerations

By Caleb Rexius

Underwater video is fun, and it can look really cool, but depending on how you capture the footage, it can be very, VERY difficult to shoot.

Here are a few common questions:

  • What camera should I use?
  • How do I see underwater?
  • How do I breathe?

Today, we’re talking about submerged cinematography. Let’s dive in.

When we’re thinking about capturing footage underwater, or even at surface level, the first decision we have to make is this: what camera do we need?

And for the sake of simplicity, I’m going to compare two primary options:

GoPro vs. a mirrorless camera with underwater housing.

And I have 3 main considerations for each option.

Let’s take a look at the GoPro first.


#1 – Very Affordable.

We’re talking around $300-400. And obviously, the uses for a GoPro go far beyond being waterproof.

#2 – Easy to Operate.

Having “auto-everything” makes it super easy to just turn on and jump in. And the wide angle ensures everything is essentially in focus. 

#3 – Durable

These things are bulletproof, and knowing it is unlikely to get damaged will take some pressure off. And even if it does get damaged, the replacement cost is low.

The Downside

The downside is that if you’re looking for a cinematic, professional looking image to your video, you’re just not going to get it here. It’s always going to look like GoPro or “action cam” video quality. 

Speaking of cinematic quality, let’s talk about using more of a “cinema grade” mirrorless camera with housing.

Camera Housing

There are a bunch of camera housing manufacturers, and my favorite is AquaTech. Most of these companies make different models to fit different cameras, so you’ll need to search and find the right fit for your camera and lens.

And be prepared to pay up. In fact, consideration #1 for a mirrorless camera with an underwater housing is this:

#1 – It’s Not As Affordable

Depending on your camera price and housing style, the housing alone might be the same cost as the actual camera. I paid around $2k all in for mine, which was the same price as the GH5 at the time (which is the camera I use for underwater video). Not cheap, but it’s pretty sophisticated, which leads to my next consideration:

#2 – Camera Control

There are a ton of nobs and buttons that interact with the camera inside, which lets you change settings on essentially everything.  And this allows for #3:

#3 – More Cinematic Footage

What’s your goal? Without a doubt, if you’re looking for that really professional “cinema-grade” footage, bringing your more expensive camera in the water (with housing) is the way to go. 

4 Underwater Cinematography Tips:

Finally, I want to end with some bonus underwater tips, regardless of camera:

#1 – Goggles

Get good goggles (or even a snorkel). I open my eyes underwater, but man, it’s a blurry mess if you don’t have good goggles.

#2 – Flippers

Get flippers. If you’re holding a camera out in front of you with both hands, you’re putting a lot of work on your legs to keep you afloat. Do yourself a favor and get flippers. Maybe even use a life jacket, but that does come with some buoyancy issues.

#3 – Wetsuit

Get a wetsuit, even in fairly normal water temperatures. When you’re in there for a long time, you get cold, shaky, shivery hands, which will prevent you from getting good, smooth, stable shots.

#4 – Slow Motion

Shoot slow-mo if possible. Like most things, water looks cooler in slow motion, and also allows for a more stable shot.

So, those are my thoughts on filming underwater. Like any question about “what gear to film with”, the answer is almost always “it depends”. But I hope this gives a little more clarity on which direction YOU should take.
