Using Filters for Underwater Video with the GoPro Hero 4, Hero3+ and Hero3

By Brent Durand



Underwater Video has been changing quickly with the HD recording capabilities of DSLR, mirrorless and some compact cameras. The GoPro Hero 4 is also a serious player due to its small size, video quality, features for underwater & topside use, low price point, and growing range of accessories. I've also been noticing a growing number of photographers building amazing portfolios with nothing but GoPro cameras.

There are many different filters available for the GoPro Hero4, Hero 3 and Hero 3+ that increase the camera’s versatility, allowing for more creative shots on land and underwater. Polar Pro makes an excellent range of glass filters for the Hero4 / Hero 3+ that we've used for the guide below (note that both cameras use the same housing). The filters snap onto the GoPro securely and easily, and the glass makes them very scratch resistant with higher optical properties than plastic. The new range of filters includes:

  • Red Filter:  Used in blue water
  • Magenta Filter:  Used in green water
  • Macro Filter:  Used to shoot small subjects
  • Switchblade 2.0 Filter:  Use Red & Macro at the same time
  • Polarizing Filter:  Used topside to control reflected light
  • Neutral Density Filter:  Used topside to slow the shutter speed

GoPro cameras can be used underwater as a dedicated video system with high-end lighting or as a more compact unit to put on the end of a pole or on top of a larger camera housing. The guide below presents an overview of Polar Pro filters for the Hero 3+ and their best uses.


Red Filter

Red filters compensate for the lack of red light in underwater scenes (since red is the first color to be lost when descending in water). This shift in available light will often confuse the camera's white balance metering, so the red filter helps deliver accurate, vibrant color in your video, as well as much-needed contrast. The Polar Pro red filter is designed to be used in tropical and blue water, optimized for use between 10 and 80 feet.

Best Use:  Ambient light (no video lights).  Blue water.

More Info & Purchase:  PolarPro Red GoPro Filter


Magenta Filter

Magenta filters also compensate for the lack of red light but are optimized for green water between 10 and 80 feet. Not only do the filters bring color back into the scene, but they also help bring back the contrast needed for interesting video.

Best Use:  Ambient light (no video lights).  Green water.

More Info & Purchase:  PolarPro Magenta GoPro Filter


Macro Filter

Polar Pro’s macro filter provides 2.2x magnification for capturing video & photos of small subjects from a close distance. The GoPro Hero 3+ has a minimum focus distance of 12 inches (you must be 12” or further from your subject for sharp images). This macro filter has a focus range of 2-18 inches, which allows you to move the camera closer to the small subject to fill the frame with more detail.

Best Use 1:  Shoot macro in combination with the Red filter (check out the Switchblade3+). No video lights are needed since the red filter brings the reds back into the scene.  Or flip up the red filter and use only the macro filter.  Or use just the red filter without the macro lens. The Switchblade is an ideal GoPro filter setup since you're prepared for anything.

Best Use 1:  With video lights, add the macro filter to capture small details – just make sure the light isn’t too strong, which will overexpose the scene.

Best Use 3:  Use it for macro shots topside!

Switchblade 2.0 Filter

* Highly Recommended for Underwater Video *

Polar Pro’s Switchblade filter combines their two most popular filters (red and macro) AND allows you to use them at the same time. As discussed above, red will correct the white balance of your shots while the macro filter will allow you to shoot subjects within 12 inches and help to fill the frame with the subject. With the switchblade you can use red and macro at the same time!

Best Use 1:  Shooting macro subjects without a video light.

Best Use 2:  Avoid the "fisheye effect" and fill the frame with your subject, delivering more detail and excitement in the footage.

Polarizing Filter

Polarizing filters are a must in any landscape photographer’s bag, so it’s natural that you should have one for using the Hero 3+ topside during dive trips. The filter reduces glare (on the water, leaves, rocks, etc) and brings a bit of saturation and contrast into bright scenes (like sky and clouds). When out on location, you can hold this filter up to your eye to preview its effect and determine whether you’ll use it.

Best Use: Topside photo and video on sunny days.

More Info & Purchase:  PolarPro Polarizing GoPro Filter


Neutral Density Filter

Neutral density (ND) filters are meant for topside use and are critical for certain video/photo situations. ND filters block light, making slower shutter speeds possible. The GoPro Hero 3+ uses a fast shutter speed by default, which freezes action very well. There are times, however, when some blur creates a sense of movement and enhances the action in the frame. The ND filter can be used to achieve this. Examples include moving pavement while driving and waves splashing against rocks.

ND filters are also very useful for timelapses, where slow shutter speeds (aka “dragging the shutter”) create slight blur, resulting in a smoother timelapse.

Best Use 1:  Video & photos with a static subject as well as a subject that needs to be blurred to show speed or the passage of time.

Best Use 2:  Smooth video, especially for GoPro timelapses or when mounted on vibrating surfaces.


The Polar Pro filters provide many creative options for your GoPro Hero 3+ (as well as the Hero 3 and Hero 2) underwater as well as topside. They will make all the difference in your underwater video and open creative possibilities for many unique shots.

Precision 5" Dome for Tokina 10-17mm Lens

Michael Zeigler
A look at this new 5" dome port for the Tokina 10-17mm lens and Ikelite dSLR housings.

Precision 5" Dome Port

Designed specifically for the Tokina 10-17mm lens & Ikelite dSLR housings

By Michael Zeigler


Looking for a dome port for your Tokina 10-17mm fisheye lens?  I was too, and that's when I found out about the Precision 5" Dome.  What's great about this dome port is that it's designed specifically for the Tokina 10-17mm lens, and my Ikelite housing.

I find that the Precision Dome attaches easily and securely to my housing via the four port-locks, and its small size makes packing easy.  But more importantly, it allows me to take some great underwater photos.

The Precision Dome details

The Precision 5" Dome is manufactured based on calculations using the nodal point of the Tokina 10-17mm fisheye lens and the Ikelite dSLR housing. The calculations define the distance between the lens nodal point and the dome, resulting in sharper edge-to-edge focus when compared to other generic dome ports. A wider angle of view is achieved from the use of a half-sphere dome.

The small size allows you to get extremely close to your subjects, which is great for close-focus wide-angle photography.

You will need the Ikelite 5510.11 or 5510.10 super-wide-angle port body with the dome. Another option is to use a 1.4 teleconverter (Kenko Teleplus Pro 1.4x) in conjunction with the Ikelite 5510.16 standard zoom port body.


Benefits of the Precision 5” Dome

  • Ultra sharp with the Tokina 10-17mm lens 

  • Wider angle-of-view

  • Better edge-to-edge image sharpness than other generic domes

  • Absolutely no vignetting with the shade

  • Small size allows you to get closer to your subjects - great for CFWA shots!

  • Very small and light - makes packing and traveling with your equipment so much easier

  • Acrylic material means light scratches will generally not appear in photos. Deeper scratches can be "meshed out" with an acrylic mesh kit.

  • All domes are vacuum leak tested

  • Includes Port Lock (for the Ikelite port body), Deluxe Dome Shade, Dust Cover, and Dome port Cover

Nauticam Viewfinder

Todd Winner
I've always been jealous of expensive viewfinders. Now I finally got to try one...

Nauticam 180 Viewfinder

by Todd Winner


I have to admit over the past few years I have become increasingly jealous every time somebody showed up on a boat with one of those big expensive viewfinders on their housing. So when Dave Hinkel offered me an opportunity to try out the Nauticam 180 Viewfinder on the Nauticam Canon 7D housing, I jumped at the chance.


Nauticam viewfinder


First Impression of the Nauticam viewfinder:

It's big and it's bright! The Nauticam 180 viewfinder gives you a much larger image of the camera's viewfinder giving you a greater advantage for critical focus and composition. The 180 viewfinder features a diopter adjustment knob that is large and easy to adjust even while wearing gloves underwater.

It does require a little practice to get used to the 180 viewfinder. I found that underwater, I had to be more precise and look directly inline thru the 180 viewfinder as oppose to still being able to focus thru the standard viewfinder at slight angles.

The LCD screen is still 100% visible even with the 180 viewfinder attached so you are still able to review your images and shoot video. Although if I was specifically doing video dives, I would leave it off just to give myself a more unrestrictive view of the LCD screen.


Installing the viewfinder:

Installing the 180 viewfinder couldn't be any simpler. The standard Nauticam viewfinder is easily removed by taking off the internal o-ring and sliding it out of the back of the housing. The 180 viewfinder has 2 pins to keep it from spinning and is held in place with an internal o-ring. Nauticam makes specially designed adapters so the viewfinder can also be used on Aquatica, Ikelite, Nexus and Sea & Sea Housings.

Now that I have had the opportunity to try one out, I'm hooked. The enhance viewfinders are an expensive accessory from any of the manufacterers, but if you can afford it, in my opinion it is worth the investment.

Sea & Sea Glass & Acrylic Dome Port tests

Scott Gietler
Sea & Sea fisheye, compact, acrylic and glass dome port review

Sea & Sea fisheye, compact, acrylic and glass dome port review

By Scott Gietler



In this review I tested 3 Sea and Sea dome ports with my Nikon D300 and Tokina 10-17mm lens in the swimming pool, checking sharpness, color and contrast.


Sea & Sea Compact dome port


The S&S compact dome port is a light-weight, 6 inch acrylic dome port. Total width is 6.5 inches including the outer plastic. 1lb 9oz with the cover and 20mm extension ring. $500 in the USA. The SX extension ring (20mm) is an additional $190.


Sea & Sea glass dome port


The S&S glass dome port is a compact 6 1/2 inch dome port made by Athena for Sea & Sea. 2lb 12oz with the cover and 20mm extension ring. $1250 in the USA. 


Sea & Sea Fisheye dome port


The S&S fisheye dome port is a 8 inch acrylic dome port. Total width is 9.5 inches including the outer plastic. 2lb 9.7oz with the cover. $650 in the USA.


Dome port test methodology


I took hundreds of test shots, at focal lengths of 10mm, 14mm, and 17mm. I took shots at distances of 2ft and 4ft away. I also compared center areas, side areas, and corners of the photos. I took photos at apertures F5.6, F8, F11. I also had two experienced photographers independently compare 100% crops of the test photos.



Glass and Acrylic dome port test results 

  • No difference between glass and compact dome ports
  • No difference between dome ports in center sharpness
  • All dome ports sharp in the center
  • All dome ports sharpest in the corners at F11, and usually fairly sharp at F8, and not too bad at F5.6
  • Large fisheye dome port (acrylic) was best of them all, but only by a small amount in the corners, if you look at 100% crops.


Dome port test conclusions 

  • Compact dome port (acrylic) is best for close-focus wide angle (CFWA) shots, and for travel, and easiest on the pocketbook.
  • Fisheye dome port is slightly better in the corners at F5.6 and F8.
  • No need to spend the extra money on the glass dome port.
  • When using the Tokina 10-17mm fisheye lens, the fisheye dome port does not need the 20mm extension ring, but may benefit from it? (This will be my next test). Rotating the aperture dial is more difficult without the ring on.
  • The compact dome port definitely benefits from the 20mm extension ring.
  • The fisheye dome port will give better results for over and under shots.
  • Glass ports are heavier, more resistant to scratching, and shed water easier that acrylic ports. It's possible that other well-made large glass dome ports have optical advantages over acrylic ports (e.g. - Subal or Seacam ports), but I didn't find any with this particular port.

Disclaimer - these test results may not apply to other manufacturers of dome ports, or in the conditions you shoot in, you should always do your own port tests. Dome ports can vary in quality.
