K&F Starlight Glare Nano-B MRC 72mm camera filter — colored rainbow flares and streaks

The K&F Starlight Glare Nano-B MRC 72mm camera filter produces colorful rainbow flares and streaks to introduce artistic light effects into photographs and video. Designed for lenses with a 72mm filter thread, this screw-in glass filter modifies point light sources into star-like, multicolored highlights while preserving the overall image sharpness and contrast. The Nano-B MRC coating reduces reflections and maintains color neutrality, making it suitable for creative night, street, concert, and portrait photography where controlled flare and streak patterns are desired.

Advantages

This filter creates vivid colored flares and elongated streaks from bright light points without dramatically degrading image quality. The Nano-B multi-resistant coating helps minimize ghosting and surface reflections, while the threaded 72mm mount ensures secure attachment to compatible lenses. The optical glass construction provides consistent flare patterns across the frame and integrates with autofocus and exposure systems without requiring post-processing to simulate the effect.

Suitable for

• Night photography and cityscapes with streetlights and neon signs
• Concerts and live events to enhance stage lights and spotlights
• Street and documentary photography for artistic highlights
• Portraits where controlled colorful rim or hair light effects are desired

How to use

Screw the filter onto the front of a lens with a 72mm thread until it is snug; avoid overtightening. Compose the shot so that bright point light sources are within or near the frame; the filter converts these into star-like, multicolored flares and streaks. Adjust aperture and focus as required — smaller apertures may change the appearance of streaks while wider apertures preserve background separation. The filter works with autofocus and metering, but you may need to adjust exposure when strong flares increase overall scene brightness.

Usage recommendations

For best results, test the filter in low-light or high-contrast scenes to determine how different light angles and aperture settings affect flare shape and color. Use a lens hood when unwanted side reflections are present and clean the filter surface with proper optical cleaning tools to maintain consistent flare quality.
