Hoya HD Circular Polarizer Filter 52mm

Polarizing Effect and Usage

Polarizing filters selectively allow polarized light rays to enter the camera lens, effectively removing unwanted reflections from non-metallic surfaces such as water or glass. They also enhance color saturation and 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.

This filter is ideal for outdoor photography, such as capturing cloud-filled skies or enhancing the saturation of water bodies. It can increase or decrease reflections on water or glass surfaces, making it versatile for various shooting conditions.

Additional Creative Use

When shooting black and white images, combining this filter with a red filter can simulate the appearance of an impending storm, adding dramatic effect to the scene.

Technical Specifications and Features

• Constructed with hardened glass offering 4 times the tensile strength of traditional filters of similar fabrication.
• Incorporates special coatings to reduce internal reflections, resulting in clearer, brighter, and sharper images.
• Provides 25% higher light transmission compared to standard polarizing films used in photographic filters.
• Eliminates ultraviolet rays to reduce haze in outdoor shots while polarizing light to remove reflections and increase color saturation without altering overall color balance.
• Enhances blue skies and makes clouds more prominent, especially when used at a right angle to the sun.
• Features an 8-layer multi-coating to minimize reflections on filter surfaces, reducing flare and ghosting.
