Adding a GoPro red filter to your action camera will significantly increase the quality of your underwater photos and videos. Use red filter while snorkeling or diving and enjoy clear, sharp images without post-processing! In this guide, we explain to you when and how to use a red filter and feature or top picks for Hero8 and Hero7 action cameras.

Why do you need GoPro red filter underwater?

Have you ever felt unsatisfied when replaying your snorkeling videos because all the footage was bluish or greenish without real colors? If it comes to underwater photography or cinematography, the biggest problem is how to get back those beautiful colors of the corals and sea creatures.

One solution is to buy a compact waterproof camera that has UW settings to correct the colors. You also can edit your photos and videos on your computer using Photoshop, Lightroom, PremierPro or any other software that can do color grading, but you need to learn how to use them, so it takes time.

What if you have a travel size GoPro Hero6 / Hero5 camera only but still want to get perfectly colored underwater footage? Although GoPro cameras deliver great quality videos and sharp images but don’t have special settings for filming underwater. There are many different GoPro accessories for diving and snorkeling like underwater GoPro lights that can help you a lot to make your footage more natural. But the simplest solution for instant correction is using GoPro red filter!

Why does everything look blue and green underwater?

Water begins to absorb colors immediately as we descend meaning colors look washed out even in shallow water. Red wavelengths are absorbed at around 5 meters (16ft), orange at 10 meters (32ft). Yellow disappears at 20 meters (66ft), green at 30 meters (98ft) and eventually blue at 60 meters (197ft).

This means the GoPro red filter is not only recommended for divers but also for snorkelers. Using GoPro red filter will instantly enhance colors and improve the contrast. Choose one of the filters according to conditions and depth, and enjoy a colorful GoPro footage!

What does a red filter do?

Underwater GoPro filters work by adding back the red color spectrum to the image. Like this, the camera can select the right white balance, meaning colors will be natural again and your underwater photos will be bright and sharp. So if you were ever wondering how underwater red filter correct colors, the answer is really this simple: just put it on and enjoy filming, the red filter will take care of the rest!

What is the difference between GoPro red and magenta filters

Underwater filters usually referred simply as red filter but it is important to know not all red filters are the same. Red filters are designed for a specific depth rate and some GoPro filter kits include additional colors like yellow or magenta filter too. You need a different filter if you dive in green water, in a freshwater lake or in the ocean according to this guide:

Red filter: use in blue water (tropical water). Generally, red filters work the best if you go deeper than 10-15 ft (3-5 m) but always check the recommended depth rate that you find on the filter itself or in the manual.
Magenta filter: use in green water. The magenta filter works the best in cold, greenish seawater or in lakes.
Yellow filter: optimized for night diving

Some brands offer snorkel filter as well (technically this is a light red filter) that is specially designed for shallow water snorkeling where a normal red filter for diving would be too much.

How to choose the right red filter

The filter you need to use depends mainly on the water conditions and on the depth of your dive. Always decide how deep you want to dive and choose a filter accordingly. Using a stronger filter won’t make your footage better but will make it too red. Our advice is to put the filters in a pouch and keep the red filter kit with you so you can change them if needed.

To avoid scratches, keep the filters in a storage bag when not in use. Before fixing the filter on your action camera, make sure that there is no sand or salt on it, otherwise, your footage might be spotty. Rinse them with fresh water after use. Use a clean, soft cloth for cleaning.

CamKix diving lens kit for GoPro pros and cons

We have tested the Camkix GoPro red filter kit for Hero4 in different conditions in the Mediterranean Sea, Red Sea, Indian Ocean and are pleased with the results. Using the right filter colors are bright but natural, and also the contrast improved. The photos and videos are more detailed when the filter is on. A nice surprise that the water seems much clearer on the footage than in the reality!

The filter holder can be mounted on the waterproof housing and fits perfectly. The Easy Clip and Slip system makes changing the different underwater GoPro filters simple and fast.


  • instantly improved colors
  • great price
  • all in one pack for various underwater conditions
  • easy installation: filter holder fits perfectly on the waterproof housing


  • changing filters could be a bit difficult because the filter fits tight in the holder (but at least it won’t slide out accidentally)
  • you need to be careful to avoid scratches

In total, Camkix GoPro red filter set works pretty well! The filters we used improved the colors noticeably, the kit has a great value for money.
