Every Landscape Photographer Needs This Filter

I follow a decently minimalist mindset when it comes to landscape photography, yet this is something I never leave home without. In some situations, this photography accessory single-handedly makes an image possible.

Polarizers, ironically, are not a very polarizing topic in the world of landscape photography. The blunt fact is you should have one, and I personally believe you cannot photograph some scenes without them. Currently living full-time on the road, I have been exploring the eastern region of the United States, which has resulted in photographing a lot of waterfalls. In that time, I’ve recognized how often my camera permanently has a polarizer attached to it and truly believe many waterfall images just don’t work without one.


So, what does a polarizer do exactly, and why is it so important in a photographer’s kit? It allows the photographer to manage and control reflections on surfaces such as water, enhance colors and contrast in foliage, and even cut out atmospheric haze in the sky. It’s an incredibly versatile tool that cannot be replicated in post-processing. You can find an in-depth look into everything it can do right here on Fstoppers, but for this article, I want to focus mainly on its strengths when photographing waterfalls. 

Polarizers almost feel like magic when you’re capturing waterfalls. Notice the difference in these two captures, which is caused just by enabling the polarizer to 100% (more on this later). Pay close attention to the foliage and how much saturation, contrast, and life gets added back into those areas. 

Notice how nearly every aspect of this image changes using a polarizer. Unlike the first example, we have wet rocks within the image, which you’ll notice just how much clarity and detail comes out when enabling the polarizer. The pool of water also drastically changes, although we don’t gain much detail, considering the result is a pretty dark area. The idea is to showcase another variable in your creative expression as a photographer.  


Using a polarizer is simple, but there are a few things I’ve learned over the length of my career that will help you understand both its strengths and limitations out in the field.

Polarizers typically also act as a 1-stop ND filter, meaning they’ll bring your exposure down by a single stop. Many times, this is helpful for photographing waterfalls, as I want a shutter speed between 1/5th of a second to half a second, but it might not be in other scenarios where you’re trying to capture as much light as you possibly can. 

Something to keep in mind when using a polarizer is that it will have varying results depending on how you position yourself between your subject and the sun. Typically, if your scene is facing away from the sun, you’ll have great results. But if you’re ever shooting in the direction of the sun, you won’t be able to cut out as many reflections. This is the case because polarizers essentially cut out reflected and refracted light at specific angles.

I find this occurs most often closer to sunrise and sunset because the angle of the sun is lower on the horizon. Thankfully, sunrise and sunset also tend to mean far less harsh light, so your polarizer isn’t as critical. This does not imply that you need direction light on your scene for a polarizer to function, though. Many times, my best results come from mildly overcast light, where enabling the polarizer cuts out a lot of reflections within the foliage of my scene (the first example in this article is overcast light).

Keep in mind that if you’re working with a very-high-contrast scene, you might not want to use the maximum amount of polarization. This was a mistake I made for a long time: approaching my polarizer like an on-off switch rather than incremental adjustment. Sometimes, polarizing to about 50-70% and leaving reflections on dark spots of water or rocks can help keep those areas from disappearing into darkness, but this will totally vary based on your scene and lighting situation. 

A great tip when using your polarizer is to make sure you are always rotating it counterclockwise or “left” when you’re adjusting the polarization from behind the camera. Make sure to reverse this if you’re standing in front of the your lens! This will ensure that you’re never accidentally loosening the filter from your lens. This works especially great with magnetic filters, because it’ll also never over-tighten the filter because your only force on the actual filter ring is the magnetic force between the ring and the filter. Speaking of magnetic filters, you might be asking what polarizer you should pick up yourself?

Which is Best?

There are a lot of options out there for filter system. The first you’ll likely encounter is a filter that simply screws on to the front of your lens. Then, you might dive down the rabbit hole of filter systems and discover square filter systems like the one above. I’ve used them all, and magnetic systems are, by far, my favorite type of filters to use in day-to-day shooting. Every system has strengths and weaknesses, but overall, a magnetic system is what I recommend to most people. 

The kit I’m currently using is made by Maven and is my current favorite filter system. Their magnets are more secure than any other magnetic system I’ve used. They’ve innovated filters in really smart ways with color coded rings, lens caps with 50% gray on the inside of them to set proper white balance, and even deliver in a convenient 3D-printed case to keep everything organized.

Regardless of what system you decide on that is best for you, just make sure you’re buying something of high quality. You don’t want to invest lots of money into taking high-quality photos and then put a cheap polarizer in front of your lens to potentially ruin your image quality. 

I’d love to see your waterfall shots in the comments or your own words on polarizers in the comments. Am I wrong? Do you ever shoot waterfalls without a polarizer? Let me know!
