I find the colours too saturated to be honest I prefer the more subdued look. But removing the glare can be a an advantage in some cases.

But whatever brand of filter you use, or want to use, the polarization filter will improve a lot of your landscape photos. Just keep in mind, there are occasions when you want to remove the filter also. Just read my article about that.

The two images above show exactly the effect of a polarization filter that is impossible to achieve in post production. The light is reflecting in the tide pool, making it nearly impossible to see through the water. But when a polarization filters is placed in front of the lens, you can see right through the water surface.

I don't believe this is exactly true. For a part, perhaps, but not completely. Because of the limitations of optics and camera sensors. a photo will never show what you see with your eyes. The same applies for long exposure or no long exposure, for example. Can you tell me what you see with your eyes? Water frozen in time, or the movement. But I never want anyone to be forced to use a polarizer. Every photographer has its own way of showing the landscape, and that makes taking photos wonderful. :)

The effect of the polarization becomes very visible when comparing a photo without and with polarization. The one without does not have those warm autumn colors. Too often I see these kind of photos of enthusiastic photographers that went out shooting the autumn forest. But when they would have used a polarization filter, the difference is amazing.

I agree with you, showing the bottom of a pool of water is not exactly what you want to do. A polarizer will remove all evident of the presents of water. But with wet surfaces it is something amazing, bringing back colors and detail, just like my examples. I think you have to be critical about using the filter, and sometimes you can just remove a bit of reflection. I say you probably need one, but you don't need to use it always

If you have a polarization filter, when did you decide to buy one? What was the reason to start using it? Please share it in the comment below. And let me know also why you wouldn’t want to use a filter like this for your landscapes. I would love to read about it.

For this version I used a part of the water from the non-polarized photo, to have more detail in the water at the foreground. I used Photoshop for this, by using layers and masks.

The large 105mm Lee Landscape Polarizer is a wonderful filter, although its large size makes it quite vulnerable at times.

Haha i do similar with the sun visor strip on my windscreen whilst driving. Then realise i wish i was out shooting rather than driving to work :(

I think Hoya is one of the best available. You can find different reviews on the internet that will tell you if that is correct (of not ;) )

Thank you for asking for comments. I wouldn't like to use a polarisation filter simply because I like to see nature as it is. Just my philosophy. Once you understand and appreciate the original, the effect is all the more worthy.

One of my favorite photography subjects since moving to Colorado has been waterfalls. I think its time to start using a circular polarizer to my shooting routine.

Excellent instructional. Learning through comparison -- seems like a good way for artistic appreciation. Thank you. I am persuaded that I need a polarizing filter.

When photographing the creek called Ninglinspo in the Belgium Ardennes during autumn, the strength of the polarization filter is obvious. Of course, the water is has gained a completely different look, showing less reflections and less white. I think it is more eye pleasing. But the most obvious are the colors of the autumn trees and leaves next to the running water. The colors are much warmer, saturated, only because of the polarization filter.

Actually, humid air is water droplets and every one of them can diffract light from any orientation. This is because they are mostly suspended spheres. A polarizer can uniquely block this incoming diffracted iight, which a UV filter cannot. This means rotating the filter until the desired effect is achieved, for fog, clouds, any atmosphere where water is suspended in air.

As long as the umbrella is 18% grey, you should be okay. I have an article available about shooting in the rain, btw/ :) https://fstoppers.com/education/shooting-landscapes-bad-weather-380546

Another example of what difference the polarization filter can make. At first I shot the bridge without thinking of rotating the polarization filter in the appropriate angle, although I had one connected to the lens. But when I saw the result, I noticed the white reflections of the light and decided to take another photo with polarization. The difference is huge, and at that moment I realized (again) how important a polarization filter for landscapes can be.

It could be discussed if this is needed in the photo I showed as an example, and that is what I was writing about in my first article. Of course you don’t need to remove the polarization effect completely. Perhaps there is a sweet spot, somewhere between reflection and no reflection. Always remember, there is a world between those two extremes.

For a long time I used the Lee Landscape Polarizer, which is a huge and expensive piece of glass, but which was worth every penny. Nowadays I use the Kase filter system, with a smaller polarization filter that works much easier, and is less prone to damages.

For a long time I refused to use a polarization filter myself. The filters are expensive and you lose about one stop of light, sometimes a little more. I believed the effect could often be simulated in Photoshop, by saturating the colors and add more contrast in the sky. And yes, the latter can be for a great deal be achieved in post-production. But not everything. Especially reflections on wet surfaces can be removed by using a polarization filter, something you cannot accomplish in post-production.

Thanks for posting this article as most of my photography is landscape or outdoor activity shots taken while on my daily hikes/ backcountry ski trips with my dogs. I'm going to put my CPL filters on my lenses today.

Polarizing filters Physics

I exchanged the Lee Landscape Polarizer for the smaller magnetic Kase system. It works very easy and is less vulnarable because its size. Because its magnetic, changing the filter from one lens to another is very easy.

I use the polarizer instead of a UV filter. For me, it is not when to use the polarizer, but instead, when to remove it.

I wrote an article about that... https://fstoppers.com/education/using-long-exposures-without-help-neutra... But that has nothing to do with polarizers. I wonder...

Oh yes, I forgot to mention all images have had post production in Lightroom, but the before and after photos received exactly the same settings. Otherwise you cannot compare the photos in an honest way.

All these photos have water as a connecting factor. And indeed, the effect of a polarization is best seen when water is in the picture. Nevertheless it could be wise to keep the filter on the lens when photographing in a location with growing plants, trees, and leaves. Especially when shooting autumn colors.

This photo of the beautiful waterfall Cascade de la Beaume in the French Auvergne shows the need for a polarization filter when shooting waterfalls and wet rocks. Without polarization the rocks of this waterfall reflect all the light, making it difficult to see the water clearly. Well, you can see it, but you know what I mean by that when looking at the photo with filter. All reflections are gone, showing the falling water in all its beauty, not distracted by any bright reflections in between.

He did say that. But he also replicated it with a handful of examples. Not sure if you watched the video of the examples viewers sent him. In my experience polarizers are way overblown. I don't love what they do to parts of the sky and I too can do what a polarizer does in post except removing the glare off of water. If I want to show the bottom of a body of water, then yes I'll throw one on, but that's not often. Horses for courses. I think it's great if one wants to use them and finds them beneficial. I also think it's a bit of a stretch to suggest that you "need" one as this article does.

You guys have already got me shopping for a polarizing filter. I plan to use it judiciously. And I am a big fan of letting the optics and sensor do the work. Less work to do in post processing.

Although I love what polarizers do to a scene, the modification removes the natural view of the scene as you see it. It's nice for an effect, but if you want the scene as you saw it, then simply shoot it as is.

The kit perhaps, but Kase is available in other packages https://www.bhphotovideo.com/c/search?Ntt=kase&N=0&InitialSearch=yes&sts...

The panoramic photo of the Ninglinspo shows the exact same result; much warmer colors and much more pleasing to the eye. Also the water has some changes, but I think in this case the water without the filter is a bit more attractive better. It is one of those occasions I was telling about in my first Fstopper article. Perhaps in this case it would be better to change the filter position to something like 60% of 70% polarisation, to keep some water detail. Or you can combine both photos in Photoshop to find the sweet spot, which I have done in the photo below. Which one you prefer is a matter of taste, there is no good or wrong in my opinion.

No, he also talked about how polarizers are mostly not needed. And from my experience he's right. There were two videos, one about how filters are mostly lame, although he relented that ND filters can be useful and even issued a challenge on polarizers...

Losing the reflectivity of the rocks and leaves is and looks unnatural. The target is less reflection and more color detail. Neither of the photos are satisfactory to my eye. Some of the photos look great but they also look like created art and not a depiction of something you can actually see with your eyes. Polarizers are a double edged sword since some aspects are very desirable but the loss of natural looking light and correct color is a big liability when you cannot get a do over. (who does a do over anyway?) I don;t know the solution since i pull out the polarizer where water is involved and hope for the best but truly have not often lamented a shot without one.

The short answer is that the sun has an illuminance of about 100k lux (lumens per square meter) on a perpendicular surface at sea level.

Thanks for the article and the images showing difference a polarizer makes. I often peak over the top of my polarized sunglasses to get a quick before and after preview of what polarizer might do to a shot.

Great article and thanks for sharing along with some great examples, such as leaves and foliage. I never would have thought about using it on scenes such as these.

Aug 19, 2021 — 44-55 seconds from flicking the switch the light will strobe for 5 seconds and then go back to normal. The lights do not strobe at the same time.

ill take it out when it stops raining, feels like England here now. so much rain. maybe i should do a review on umbrella's for photographers. hehe, buy a normal 10$ umbrella, label it wescott and charge 400$ for it.

Good advice. I wish I had more time for using my filter, but it slows me down way more than is good for me when I'm out with my family. Have done that at many occasions, and I was always running after them.

The example of this landscape from the French Auvergne clearly shows what difference a polarization filter can bring. The colors not only became much warmer with polarization, but the sky has a completely different look. You can much better into the distance, and see the clouds in above the horizon. The filter can eliminate much of the haze. Again, post processing for both images are exactly the same.

The effect on water is the most obvious reason for choosing a polarization filter, of course. I have seen people remove the filter when they are not photographing water. Like between mountains, when shooting into the distance. The effect of the polarization can be quite stunning of you are able to place a before and after photo next to each other.

Besides not polarized and polarized, you can also meet in the middle; just a little bit of polarization. It can prevent from removing the water completely. After all, you want to show the water most of the times.

A little more than a year ago I wrote my first article for Fstoppers, about a polarization filter and when not to use it for landscape photography. Yes, there are moments when it is better not to use such a filter. But for a lot of other situations it is advisable to have a polarization when shooting landscapes, something I did notice again last month, when shooting the autumn colors in the Belgium Ardennes. When I saw a couple of photos of that region by fellow photographers, I could easily pick out the photos without a polarization filter.

PR Rao · 2014 · 5 — In this work, we report the performance of 4-transistor backside-illuminated CMOS image sensors (4T BSI-CIS) in the extreme ultraviolet (EUV) range.

The polarization filter is more than making the sky blue and looking through water. It can really improve your landscape photos. Let me show you why you should use one.

Just put it on you lens, and don't remove it. Just a turn of the filter can make a difference. But not inside or during darkness, because you will loose 1-2 stops of light because of that filter

I shoot landscapes.... so 90% of what I do is on a tripod. In most cases, f-stops and depth of field are more important than shutter speed unless it is windy. Like I said in my first post, I remove the polarizer under certain circumstances where getting the shot is more important than all of the esthetics. When I shoot nature, it's off, when I know that I am going to create a black and white image, I generally take it off unless there is a lot of haze, if I am doing something after dark, it's off.... For nearly everything else it's pretty much on. However, discretion and compromises must be made. Your point is certainly valid...

I'm not adverse to polarizers, I like very much what they do, but it's certainly not natural. It is a great creative tool tho. Blending the two styles is also creative and, typically, a good way to replicate a scene closer to what it was. If desired, of course. :-)

Tony never said that. He was referring to ND filters and stacking. He explicitly said that the polarizer is the only filter you actually need because it can't be replicated in post-processing.

Illumination, founded by Chris Meledandri in 2007, is one of the entertainment industry’s leading producers of event-animated films, including Despicable Me—the most successful animated franchise in cinematic history—as well as Dr. Seuss’ The Lorax, Dr. Seuss’ The Grinch and The Secret Life of Pets and Sing films.

Illumination has an exclusive financing and distribution partnership with Universal Pictures.

Every wet or moisture surface can have reflection. Even laminated surfaces. But also amphibians, and mushrooms, and even insects

I respect your philosophy. Everyone has their own preferences, and that is good. This way, every photographer shows his or her interpretation of the landscape.
