The wide range of GoPro accessories marketed to underwater video shooters can seem daunting at first. Should you use GoPro filters? Video lights? Both? And what about editing to change the color of your footage… that’s what the pros do, right?
This article will explain filters, video lights, color correction and when to use each technique for underwater GoPro video.

When do you use Filters, Lights, and Manual Color Correction?
Great color can help take your underwater video from good to great. As divers, we learn (and then see firsthand) how color is lost as we descend in the water column. The light also becomes less intense and the contrasts near the surface become more muted. To bring back the rich colors of the reef and marine life, divers often shine a light or torch, photographers pop strobe flashes, and videographers use GoPro filters, video lights and/or manual color correction.
We use all three of these options to bring the red and other colors back into the scene, delivering a more interesting, color-accurate image. Accurate color balance renders whites as neutral… in other word, they will look white. Some might argue that the dull blue or green ambient tint is most-realistic since that’s the underwater view without artificial light or filters, but the majority of videographers prefer to use these tools to create more pop in the image.
So how does underwater color correction work? How do you choose between filters, lights and manual color correction when shooting GoPro video? Let’s break it down to the basics.
The most common GoPro filter is red in color, designed to be used in clear blue water. Red is the first color lost as we dive deeper into the water, and this filter adds red back into the scene as we descend past 15ft (5m). Magenta filters are generally used in green water.
The GoPro is always looking at the color in the scene and determining the white balance it determines most accurate. When the red filter is applied, the GoPro sees red and selects a warmer white balance (which is measured by kelvin temperature) that makes whites and grays actually look white and gray.
When to Use GoPro Filters
GoPro filters are best used below about 15ft (5m). Above this depth the sunlight can be really bright, with red already existing in the water. If you use a filter in this situation you’ll see a red tint in the image, especially when shooting towards the sun.
SHOOTING TIP: Shoot with the sun at your back when using a GoPro filter. By doing this, more of the scene is lit by the sun, is brighter, and will deliver better color through the filter.
GoPro Video Lights
Video lights are the best choice for shooting any scene where you’re within about 5ft of the subject (fish, reef, sharks, scuba diver, etc.). This is one of the few pieces of gear where spending more money will buy better results, since the stronger the light (the more lumens), the more vibrant color you can produce while shining through more water. On top of that, two lights is ideal with the GoPro unless you’re specifically shooting macro.
When the lights are on, the GoPro will detect all the color, delivering an accurate white balance for the scene. Ideally, you will mount your GoPro on a tray and handle system, which not only helps keep the GoPro steady, but provides a place to mount adjustable arms and clamps for the lights. This rig provides a comfortable and stable way to hold the camera, plus the flexibility to move the lights around to create the best lighting for the scene.

When to Use Underwater Video Lights
Video lights excel over filters anytime you’re within a 5ft range of the subject, as the color and contrasts really pop.
Can you Use GoPro Filters and Video Lights at the Same Time?
No, you can’t use a GoPro filter and video light at the same time. You can use filters for wide underwater scenes and lights for subjects close to the camera, but if you use both at the same time, the footage will appear red. This is because the white light is already bringing color back into the frame, and if you then apply the red filter, it’s like looking through the filter on the surface.
Manual Color Correction with GoPro
Color correction refers to manually adjusting the white balance of the scene, whether in the camera itself or on the footage while editing on the computer, tablet or phone. The goal is to make the color white (or a neutral gray) look true to life with no blue or green tint.
Many serious videographers will rely on their camera’s manual white balance feature underwater, using a white slate or other object as a reference for the camera to adjust kelvin temperature until the slate looks like a true white. GoPro cameras don’t have an automated process like these more advanced compacts, mirrorless or DSLRs, so the best option is to get the color as accurate as possible through use of a filter or lights, and then address subtle color correction during post processing.
The goal is to get the color as accurate as possible in-camera, since image quality deteriorates when making big adjustments during post processing.
Most video editing software includes an easy-to-use white balance adjustment tool, often a dropper icon, that automatically adjusts white balance when you click on an area of white or neutral gray in the scene. I use Adobe Premiere Pro, however iMovie and Windows Movie Maker are great free alternatives.
After you make this initial white balance adjustment, you can play with color wheels to make small changes until the white balance looks good to your eye.

GoPro Filters Buyers Guide
There are quite a few choices of filters and lights for your GoPro. Filters are specific to the GoPro Super Suit, but luckily Backscatter’s kits below fit all the latest models. Smart. Video lights are available from many manufacturers with different features, lumens, and of course, prices.
All the gear below will help you take your underwater GoPro footage to the next level.
Single Filter Kits
Single GoPro Filter kits are perfect for those that want a single filter. This could be a red filter for blue water, a shallow filter, deep filter, or others.
Most filter kits allow you to swap out the filter, so while you are limited to one filter on a dive, you can change them out based on dive conditions and dive profile.
Backscatter FLIP6 Single Filter
Simple, easy flip-on / flip-off filter for underwater video. The included DIVE filter is the best all-around filter for scuba diving. $39 – FLIP6 Single.
PolarPro DiveMaster Filter Kit
Fantastic filter set that fits snugly on the Super Suit dive housing. The kit includes red and magenta filters so you’re ready for any wide-angle video shooting. The case is really cool too! $39 – PolarPro DiveMaster.
Double Filter Kits
Similar to the single GoPro filters, but with two hinges so that you can use two different filters on the same dive. You can gear up with a shallow and deep filter, red and magenta filter, or even a red filter plus macro lens for subjects closer than GoPro’s 12″ minimum focus distance.
Backscatter FLIP6 Three Filter Kit
Set up your GoPro to handle all your dive conditions. This kit includes the DIVE filter, plus a shallow water and green water filter. They are interchangeable . $79 – FLIP6 3.
Backscatter FLIP6 Pro with MacroMate
This kit includes the three filters above plus a +15 Macromate Mini. Your GoPro alone cannot focus closer than 12″, so even in Narrow FOV you still can’t really shoot macro. The Macromate Mini allows you to shoot at a closer distance, and magnifies the scene, so you can capture those macro critters! $159 – FLIP6 + MacroMate.
PolarPro SwitchBlade 7 Filter Kit – My Favorite!
High-quality and versatile, the SwitchBlade 7 is my favorite filter set for the GoPro Super Suit housing. Add a red or magenta filter to the top hinge, a macro lens to the left hinge for small subjects and you’re good to go. The kit also mounts directly to the GoPro base, meaning it can’t get bumped off and lost. The padded case is rad too, making you feel like a pro! $79.99 – SwitchBlade 7.
Backscatter Wide-Angle Filter Kit
GoPro Video Lights Buyers Guide
GoPro video lights bring the color back into your underwater footage, at least with subjects that are within 3 feet (1m). A single light is great for fish portraits and smaller subjects, but two lights is ideal for reefscapes, big animals and other large scenes.
Video lights are one of the few items where I recommend spending more. This is because a higher budget simply buys more lumens. The more powerful light will better light your scene, especially if further away.
Here are some great GoPro video lights at various price points. These will work great for all GoPros, including the latest HERO8.
Kraken Hydra 1200+ WSR
Retail: $179.99: Hydra 1200+ WSR
Light & Motion Sola Video 2000 S/F
Retail: $399.99: Sola Video 2000 S/F
Light & Motion Sola Video Pro 3800
Retail: $699.99: Sola Video Pro 3800

(Filmed on GoPro, unedited)
GoPro filters and underwater video lights are the best tools for creating vibrant images with white balance as close to accurate as possible. To take your color preferences one step further, you can make subtle color corrections while editing the footage.
- Filters are best used in clear water with subjects that are farther than 5ft away.
- Underwater video lights are best used for close subjects and a tray/handle system.
I hope this article helps you pick out the perfect filter set for your underwater GoPro video.
