Multi-Coating Polarized Camera Lenses

Designed for use with auto-focus and non-auto-focus cameras, the AmazonBasics circular polarizer features a multi-coating on the surface that reduces reflection when shooting in low light. The multi-coating offers not only better-looking photographs, but also exceptional convenience – no need to take your filter on and off when the light changes.


Essential for Outdoor Photography

One of the most popular special-effect filters, the circular polarizer helps outdoor photographers – professionals and aspiring enthusiasts alike – capture that awe-inspiring image.

Unlike a static single film polarizer, the circular polarizer gives you control over the angle of the polarizing effect in relation to the light.

By reflecting certain light rays, the polarizing filter only allows select light rays to enter the camera lens. From vibrant sunsets over the ocean to vast mountains and grand canyons to family photos in the backyard, the AmazonBasics circular polarizer will help take your outdoor images from simple to sublime.

The Essence Of A Polarizer In Photography

If there is one important digital camera accessory that professional photographers carry other than the lens, it has to be the polarizer. Professionals using DSLRs or large format movies usually have several types of this accessory.

There is no denying that the polarizer works wonders with images. It has been used even before the introduction of photo enhancement software known as Photoshop. First, this camera accessory improves the appearance of a scene by reducing or eliminating glare and improving the overall color saturation. For example, you can darken a blue sky to create a deep, crisp blue.

Compared to today’s software programs that many people and professional photographers use today to edit their photos, the polarizer effect is unbeatable. The good thing about this is that being a filter, it only allows certain light waves to pass through. As such, it eliminates glare often seen on light-reflecting subjects and surfaces. The result is rich color in the images you capture.

The polarizing filter often comes in a circular shape and is worn by mounting it on a plastic disc that has a metal or plastic ring frame that can be rotated. This is attached to the lens by screwing or clipping it at the front. Thread type is ideal if you use only one lens. It’s also good to use if all your lenses have a similar filter thread.

The circular polarizer is designed for SLR cameras with autofocus function. However, it should be understood that it can also be used on manual cameras.

In terms of thickness, experts strongly recommend using the fine polarizer. The reason is to avoid the problem of vignetting or darkening in the corners of a photo that often occurs when using thick type. The thin type of polarizing filter may cost a bit more and should be used in conjunction with wide-angle lenses if possible.

When using this digital camera accessory, it is helpful to know the effects it creates. Before shooting, you must first rotate the filter to get the effect you want to achieve. Note that rotating the filter creates a varied effect.

The polarizer is the best for landscape photography. For those who take photos of scenic locations that include bodies of water such as the river, this accessory can help you achieve a more detailed image by reducing reflections. When photographing a river, for example, you can make the water appear transparent by using the polarizer. Also, it is a good idea to use this filter when capturing foliage images.

It is very important to adjust the polarizer whenever you use it. You must know the effect you want to achieve, so if you are not satisfied with what you see, always adjust it and take another photo. It would also help if you take another photo of the same scene without the polarizer so you can see the difference.

 


Polarizer Filters in Photography

Polarizing filters designed for use in camera lenses consist of a plastic sheet called Polaroid (manufactured by the Polaroid Corporation), or a basically similar material manufactured by other companies, capable of limiting the transmission of polarized light to, or near, a single plane. polarization.

(Most polarizers are made by absorbing iodine onto a thin sheet of polyvinyl alcohol which is then stretched to align the molecules in long parallel chains. The resulting filter material has the ability to plane polarize a beam of light or to absorb light. already present (plane-polarized.)

The polarizing material is sandwiched between glass sheets and is usually encased in a screwed filter frame such that the filter can be rotated after mounting on the lens. (For uses that require large parts, Polaroid is also available in unprotected sheets of different sizes and proportions.)

In outdoor photography, natural polarization affects only part of the light that makes up the image. Unpolarized light is transmitted through a Polaroid photographic filter at a standard rate of approximately 40%, regardless of rotation.

However, light that is already naturally polarized is transmitted at rates ranging from the maximum rate of 40% to as low as 1 or 2%, depending on the angle of rotation of the plane of polarization of the filter with respect to the plane of polarization of the filter. filter. light.

That is, when the plane of polarization of the filter is parallel to the plane of vibration of the light, the polarized beam is affected only by the non-polarized light.

But when the filter is rotated away from this alignment, the percentage of transmission decreases until, at a 90-degree angle with the plane of vibration, the absorption of the polarized part of the light by the filter is almost complete. A polarizing filter can also be used to polarize a previously unpolarized beam.

Some cameras incorporate polarizing elements in their light measurement and display systems that make it impractical to use ordinary (linear) polarizing filters – the meter will not read correctly. With these you must use a “circular” polarizer; the term refers not to its shape but to the nature of its polarizing effect.

Circular polarizers are somewhat more expensive than ordinary polarizers and can be a bit more difficult to come by. In photography, once the problem of measurement is solved by using it, a circular polarizer works in the same way as a normal one.
