Are all circular polarizers the same?

The short answer is that both Linear and Circular Polarizers do the same thing. The actual polarization effects such as reducing reflections on glass surfaces, increasing color saturation in foliage, darkening a blue sky are the same with both Linear and Circular polarizers.

How do I know what size polarizing filter to get?

The filter needs to fit the diameter of your camera’s lens therefore check your camera lens first. The diameter size is indicated on the top in millimeters (Ex: 16mm, 35mm, 50mm, 55mm, 65mm, 77mm, 82mm, 100mm, 300mm, etc.). In theory, one polarizing filter of the correct size should fit all.

Does circular polarizer reduce light?

Standard high-quality circular polarizing film will reduce the amount of light entering the camera by 1.5-2.5 stops. HRT, or High Rate Transparency (High Transparency) polarizing film is both thinner and uses a slightly different material to filter out polarized light.

Is ND filter same as polarizer?

While both are quite similar and occasionally confused with each other, it must be noted that the ND filter is better at blocking light and the polarizing filter directly affects and intensifies colors within an image.

Are cheap polarizing filters good?

They reduce unwanted reflections in water and glass, as well as enhancing the colour of skies by cutting out haze. It’s an effect that can’t be replicated easily in post-processing, which is why an inexpensive polarizer is such a good buy for pretty much any photographer.

Can you use a circular polarizer at night?

Wrapping Up. A circular polarizer is definitely worth putting in your toolkit for night photography. ‘Nuff said.

Is a CPL filter the same as a polarizing filter?

The two types of polarization A circular polarizing lens filter, or CPL, therefore, filters circularly polarized light. But, it is also sensitive to linear polarized light. A CPL filter is basically a linear polarizer, but with an extra optical glass element behind it.
