A circular polarizing filter (CPF) is one of several creative tools you may use to improve the final shot that displays on your camera’s LCD screen. It is the greatest camera accessory for landscape photographers since it helps you to capture vividness and contrast in your photos. In case you want to learn what circular polarizing filters are and how you can use them, then this guide is all that you need.
Circular Polarizing Filter
A polarizing filter on your lens is similar to putting polarized sunglasses over your eyes: the polarized glass prevents random light waves from going through, resulting in a crisper image. Circular polarizers, on the other hand, feature an additional quarter wave-plane element that aids in the conversion of light into a form suited for current autofocus and auto-exposure systems.
Early filters were acceptable with linear polarization because this technology didn’t exist years ago, but if you’re purchasing today, circular is the safe pick. What polarizing filters do is both easy and difficult to comprehend. A circular polarizer helps to decrease reflections and glare by filtering out light that has become polarized owing to reflection from a non-metallic surface.
Essentially, it reduces specific types of light in a way that benefits your photography. It will, in particular, minimize glare and reflections, as well as some haze. This can assist in decreasing reflections on glass or water, diminish reflected light on specific things, or increase overall contrast in a landscape in real-world applications.
In addition to the standard circular polarizer, you may have heard of linear polarizers. Both filters achieve the same purpose in practice but a little difference to notice. When applied at the precise angle for maximum polarization, both a linear and circular polarizer have the same identical impact on your picture in photography.
A circular polarizer filter, on the other hand, has a second layer of material called a quarter-wave plate that converts linearly polarized light from the polarizing layer to circularly polarized light. Because linearly polarized light can cause both autofocus and metering to fail, this is required on most current cameras.

How Does A Circular Polarizing Filter Work?
A circular polarizing filter can do wonderful things for both outdoor and interior photographers. This is due to the way a polarizer works, as well as how light operates at an atomic level. Instead of the endlessly variable angles that light waves might travel at, a reflection is formed by waves of light that are polarized in predominantly one linear direction.
Realistically, digital cameras are difficult to understand and operate. The Menu systems are filled with several options, making it difficult to get a perfect uniform setting. However, one must understand them to capture good photos.
We know that understanding the various types of cameras, settings, and techniques can be overwhelming if you are new to the photography industry. Thus, we have provided this master article – camera 101, to help all beginners and even experienced photographers understand their cameras.

Because of its atomic structure, a polarizing filter can only pass light from one polarization, and if that angle does not match the angle of the reflected light, it is partially or completely blocked.
Note: Being very slightly blocked if the polarization angle is approximately the same, and virtually completely blocked if the polarization angle is 90 degrees different from the polarized light angle.
How Do I Use A Circular Polarizing Filter?
There are some simple steps that can help you in understanding the proper way and use of circular polarization filters.
- To begin, apply your polarizing filter to your lens or your filter holder.
- After that, you’ll want to tweak the filter in small increments to examine how the changes in the filter’s location affect the entire scene.
- A ring on a circular polarizing filter may be rotated. To activate the polarizing effect, simply twist the ring.
- As you turn the filter ring, keep an eye on your image through the viewfinder or LCD.
- As you spin the polarizer, you’ll notice that the amount of glare and saturation in the shot changes.
Note: The polarizing effect of your filter is strongest when you photograph at a 90-degree angle to the sun, so it’s ideal for side-lighting compositions. The highly polarized effect will be non-existent when the sun is behind you at 180 degrees. The amount of polarization will vary between these two locations. When you get maximal polarization, reflections disappear and the contrast between the blue sky and the structure of the clouds becomes more noticeable.
Make careful to practice with reflections, water, and the sky as you learn to utilize your polarizing filter. To compare the results, take a series of photos of the same scene with varied amounts of polarization, from zero to maximum. The distinctions should be significant. It’s vital to remember that after your filter is mounted, you should always manually focus before turning the polarizer.
Because the front ring of the lens to which the polarizer is mounted can spin while you are focusing, the polarizing effect can be accidentally changed. Once you’ve mastered the usage of a polarizing filter, you’ll discover that it’s beneficial even if your image doesn’t contain any sky, water, or reflections.

When Should You Use a CPL Filter?
There are several reasons why a circular polarization filter is of great use for everyone.
Pro tip: While getting acclimated to the polarizing filter, practice with reflections and blue sky. Compare and contrast images of the same scene taken with and without maximal polarization. There should be a significant difference.
Improving The Vibrant Feel
Autumn is when the filter shines brightest, when nature’s colors are at their most vibrant. The CPL filter may enhance contrast, vividness, and color to images of foliage or woods. It has the ability to turn nature into a richer palette of hues. Such a filter may also remove reflections and shine from foliage, trees, and plants, resulting in clean, distraction-free pictures.
Removing Glass Reflections
Photographers use a circular polarized lens filter to reduce distracting light streaks and glare that invade an image while shooting through a window or of glass structures. When individuals first start out in photography, one of the first things they notice is how difficult it is to snap images through a window.
The polarization effect, which can eliminate all those unwanted light streaks that obscure the subject of your image, is available with a polarized filter. It can also perform the same thing with light reflected off water. Photos of painted objects, such as cars or buildings, produce a lot of shine and reflections, therefore such a filter can help.
A CPL filter also reduces glare from reflected surfaces, making images more clear. However, if you’re photographing rainbows, which are formed by glare when the sun’s rays and moisture collide, increasing the glare intensity can actually improve the color and clarity of the rainbow.
Rich Color Tones
A circular polarized lens filter can also be used to generate deeper, richer, or more intense tones. If you want to create drama, mood, or even a sense of tension to an image, this is extremely important. Experiment with the filter’s rotation to achieve the ideal result, blending a natural feel with a surrealism aesthetic. Shoot at a 90-degree angle from the sun or light source to get the best linear polarization effect.
Reduced Water Reflections
The filter decreases dispersed light and eliminates reflections of the sky or other things on the water’s surface, which is very useful for photographing water or wet surfaces. The reduction of reflections from non-metallic surfaces is one of the most popular applications of a circular polarized lens filter.
Any outdoor photographer will be all too acquainted with the annoyance of reflections, especially when the sun is shining brightly. These reflections can easily detract from the subject of a photograph. Using such a filter on the camera lens might assist to reduce distracting reflections. This allows the water’s detail, as well as the surface underneath it, to show out.
Reduced Haze
Photographers who capture distant views like mountain ranges or cityscapes have noticed that circular polarization filters lower atmospheric haze in the same way that UV filters do. A circular polarized lens filter can correct and add contrast to photos where aerial or atmospheric haze affects image clarity. As a result of the improved clarity and color saturation, remote objects may look crisper.
Changing Sky Shades
A darker, more menacing-looking sky will assist give your landscape image a more frightening feeling of suspense. The same may be true for interior pictures if the goal is to create a menacing vibe. Because you could want to raise or reduce the amount of color depending on what you’re trying to create, this example blurs the line between when and when not to use a polarization filter.
The CPL would be useful in this example if you were trying to add color to a blue sky. You may adjust the color impact of your images to create greater contrast by using CPL filters, which block out particular wavelengths of light. You can achieve this with a decent CPL filter without making the scene appear weird. If you’re photographing the sky, for example, the filter might make boring clouds look more visually appealing or lend a deeper tone to the blue.
How to Use a Polarizing Filter For Capturing Images
When photographing subjects at quite a distance, a polarized filter is essential. The greater distance between you and the light you’re catching, the more important it is to polarize it. A shot of a building or a city from a distance can be an example of where polarization filters are useful.
When employing a CPL Filter, there are a few things to keep in mind.
- Don’t always utilize the highest polarization level.
- It reduces the amount of light that enters the room.
- When possible, avoid using a wide-angle lens.
Although some haze and softness may be captured in the scene, it is useless without the polarizer if you capture it with an ordinary lens. A polarized filter can help reduce haze and improve the clarity of distant buildings and subjects, even if they are relatively close.
When Should A CPL Filter Not Be Used
Using a circular polarizing filter with a wide-angle lens is typically not a good idea. This is because CPL filters operate best at a 90-degree angle from background light, such as the sun, and a wide-angle lens often covers more than 90 degrees.
On cloudy days, test it out. Depending on the angle to the light, the polarizer helps saturate a blue sky. There is no blue if it is gloomy, although it may lend a touch of zing to darker clouds. Use it to minimize glare that robs color saturation by removing flat grey sky reflections onto glossy objects.

FAQ’s
Is it possible to use a circular polarizing filter indefinitely?
A polarizing filter should not be left on your lenses at all times since it lowers light transmission and might cause the sky to seem unevenly graded when using wide-angle lenses.
Is it possible to combine a UV and polarizing filter?
When employing a polarizer, the UV filter has no effect. Each filter marginally weakens the photos, and stacking them raises the risk of vignetting. As a result, you should avoid using them together.
Is it possible to apply a polarizing filter indoors?
Indoors, only use a polarizer if you have a special requirement to reduce reflections. It’s mostly employed for a particular effect before being removed once the photo is taken. When you don’t need to, you automatically lose two stops of light.
Should I use a circular polarizing filter while photographing people outside?
A lesser-known consequence of a circular polarizing filter is that it flattens an image’s contrast. This is especially useful for outdoor portraits. Using a filter to reduce contrast is a useful method to capture more detail in a photograph.
Are CPL filters a good investment?
There are many other things you can live without, but a CPL accomplishes so much that you can’t do without it. It’s significantly more crucial than any other filter, and you should almost always have it on your lens.
