Freewell Black Glow Mist Filter for OSMO NANO — diffusion/mist effect

The Freewell Black Glow Mist 1/4 filter is a screw-on diffusion filter made for the DJI Osmo Nano. It produces a subtle glow around bright points in the frame, softening highlights and slightly lowering local contrast to create a cinematic, atmospheric look while preserving image detail. The filter is intended for both video and photo use when a gentle mist or diffusion effect is desired.

Advantages

This filter provides a controlled, delicate bloom on bright areas without significantly changing exposure or color balance. It is specifically sized and threaded for the Osmo Nano, allowing fast and secure attachment. The effect is subtle and repeatable, making it suitable for users who want softer skin tones and reduced highlight clipping while keeping overall image clarity.

How to use

Screw the filter onto the lens mount of the DJI Osmo Nano until it is secure but not overly tightened. Compose and expose your shot as usual; the filter will gently diffuse bright points and soften highlights without requiring camera exposure compensation in most situations. Remove the filter when a neutral, high-contrast image is needed or when using ND/polarizing filters that are not compatible with the mist filter.

Recommendations

Use the filter when you want a subtle cinematic glow — for example, portrait video or night scenes with point light sources. Store the filter in its case and clean the optics with the supplied cloth to avoid scratches and maintain consistent effect quality.
