Hoya Slim Circular Polarizer Filter 49mm

Polarizing Filter Functionality

Light rays reflected from surfaces become polarized. Polarizing filters control which light rays enter the camera lens, effectively removing unwanted reflections from non-metallic surfaces such as water or glass. They also enhance color saturation and improve 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 its orientation relative to the sun.

Applications

This filter is ideal for outdoor photography, such as capturing cloud-filled skies or enhancing the saturation of water bodies like oceans or lakes. It can increase or decrease reflections on water or glass surfaces, making it versatile for various shooting conditions. When shooting black and white images, combining with a red filter can simulate dramatic stormy skies.
