[in Frame] LPRF 100x100mm for HT100 IV

KANI Light Pollution Reduction Filter 100x100mm with Filter Frame

The KANI Light Pollution Reduction Filter (LPRF) is designed to reduce unwanted color casts caused by artificial light pollution, including city lighting, sodium-vapor lamps, mercury-vapor lamps, and other urban light sources.

By effectively cutting excessive yellow-toned wavelengths, the filter helps restore more natural color balance and improves clarity when photographing night scenes, cityscapes, stars, and other subjects affected by ambient artificial lighting.

KANI's LPRF is particularly known for its excellent suppression of yellow light pollution, making it an ideal choice for photographers who want cleaner, more neutral-looking night images directly at the time of capture.

Why Use a Light Pollution Reduction Filter?

Artificial lighting can introduce strong yellow, orange, or green color casts into night photographs, making skies look unnatural and reducing color separation in the scene.

The KANI LPRF selectively reduces problematic wavelengths from common artificial light sources, helping produce cleaner skies, more natural colors, and improved overall contrast. This can also reduce the amount of color correction required during post-processing.
