Does a GoPro require a polarising filter to achieve good shots through the surface of water?

Re: Does a GoPro require a polarising filter to achieve good shots through the surface of water?

It depends. This isn't so much a GoPro question as just a camera photography/videography question. If you are above water and there is sun glare on the water, then a good polarizing lens will reduce or eliminate the glare allowing the view to be below the water (if the water is clear).

Re: Does a GoPro require a polarising filter to achieve good shots through the surface of water?

Thank you, I suppose in hindsight my question would have been, does a GoPro have a built-in polarising lens.  Accordingly, my next task is to find lenses and filters designed for GoPro cameras.

 

Thanks again for the advice.

Re: Does a GoPro require a polarising filter to achieve good shots through the surface of water?

GoPro cameras do not have an internal polarizing lens. There are different types of filters that you can purchase. You can find lenses that snap over the camera's protective lens, some that replace the protective lens, and then there are adjustable circular lens that require a modified housing with a standard lens thread. Each has it's advantages and disadvantages.

The snap on are the easiest to use, are generally much cheaper, but offer the least amount of performance.

The lens that replace the protective lens remove the extra layer of glass that occurs with snap on, are more secure, and are relatively easy to use, but are not as convenient as the snap on and work moderately well. These are the lens you want to get if you are taking your camera under water.

The circular polarizing lens are usually adjustable so they give the best performance but require a housing or adapter with a 52mm thread for the lens to screw into. They usually work well for 16:9 Wide or Linear FOV but will create a vignetting in 4:3 photos or video and when Superview is used.

Everything I've mentioned above address the different types, but no matter what you get, if it's not high quality, it's going to degrade your image significantly. Cheap does not usually equate to a good deal as spending less for a lens that is unusable is just a waste of money.
