This camara is used on my kayak fishing trips, so it will get splashed and I'm probably going to be dunking it in the water too for some underwater shots of my fish.

Thanks in advance
Dan


I dont use Rainx and Im pretty sure its not a good idea with a polarizing filter. I have used the blurfix and Marumi cp on the water with the spit and dip method which has worked well on the waters surface. You just need to repeat this fairly often so if you cant get access to it easily on your kayak you may need some other method that wont damage the filters coating.

Nice, would you mind sharing your source in HK?

The alternative I did involved identifying online and buying an 8 x 11" sheet of polarizing film from Hong Kong for $1 (shipping included), cut out a round "lens" the appropriate size, identified the horizontal orientation that is most useful (like sunglasses...that is the best orintation 95% of the time) shoved/wedged it into the housing "lens". And voila' it works! And I have a lifetime supply of replacments.

I have tried that myself. The problem is that the camera lens and the cover lens are both curved, making the space between them curved as well. That forces the disc of polarizing film to bend, and polarizing film changes its orientation in response to stress. I checked the polarization with the filter installed, using a polarized light source, and found large blobs in the image indicating different polarization. It was also evident in the reflections in the windshield when I mounted the camera in the car. The center of the image was good, but the corners still showed strong reflections.

Here is a little snowboard edit from Canada earlier this year using the Hero, blurfix and CP with no colour work in post, needs musics but I couldn't think of anything so will add it later. :mrgreen:

Amazon just delivered me a Tiffen circular polarizer (55mm). I use it on SRP blurfix, it fits perfectly. The problem is a terrible vignetting, here's photos (sorry for the poor subject):

Tiffen circular polarizer 720p

no filter 720p


So, seems that tiffen filter is not a good solution for gopro: the borders are too high and appears in the shot

You will need to grind down the filter a little which is what SRP do with the filters they have as there is not much room to play with due to the high fov camera. Check the blurfix discussion thread a few people have mentioned how they have ground theirs down.

Here is a video of the Hero3 Black using the new Blurfix3 SO adapter and marumi CP filter rotating it to see the effect on the glare coming off the lake.



More info will be in the Blurfix discussion thread and I will do a full review once I get a final retail version of this new adapter.

Does anyone have any experience with using the Gopro3 Black with a polarizing filter in combination with Protune ?

I'm afraid you're gonna lose allot of detail in the shadow area's
