Hoya HRT Circular Polarizer Filter 46mm

Polarizing Filter Functionality

Light rays that are reflected become polarized. Polarizing filters select which light rays enter the camera lens, removing unwanted reflections from non-metallic surfaces such as water or glass, and saturating colors to provide better contrast. The effect is visible through the viewfinder and can be adjusted by rotating the filter. The filter factor varies depending on the rotation and orientation relative to the sun.

Applications

This filter is ideal for outdoor photography, such as capturing cloud-filled skies or enhancing water saturation at the beach or mountains. It can increase or decrease reflections on water or glass surfaces, making clouds stand out and improving overall image quality. When shooting black and white, a red filter can simulate a threatening storm effect.

Essential Gear

Alongside UV or Skylight filters, a polarizing filter is essential for photographers, transforming ordinary images into creative photos by increasing color saturation.

Hoya HRT Circular Polarizing Filter Features

The Hoya HRT circular polarizing filter features a unique High Rate Transmission (HRT) film that allows more visible light to pass through while maintaining the same degree of polarization. This results in approximately 1/3 stop more light intake without reducing polarization effectiveness, benefiting digital and HD camera users. The HRT film technology is also used in the latest HD LCD TVs. Additionally, the glass has UV absorbing properties, making this filter a combination UV and circular polarizer.
