Diffusion camera filter Hoya Mist Diffuser Black No1 72 mm

The Hoya Mist Diffuser Black No1 72 mm is a diffusion camera filter that produces a soft black mist effect by evenly distributing a fine black nano powder between two layers of optical glass. With an uncoated glass surface to enhance flares and preserve the intended look, the filter is designed to add a subtle cinematic quality to photos and video without whitening the image. The No1 version delivers a stronger diffusion than No0.5 and is suited to scenes with forward lighting or low light.

Advantages

The Mist Diffuser Black No1 creates controlled diffusion around light sources and slightly reduces shadow contrast for a film-like appearance while maintaining overall image tone. Its construction uses an aluminum low-profile frame to minimize vignetting and provide durable yet lightweight mounting. Because the diffusion is achieved within the glass layers, the effect is consistent in-camera and reduces the need for post-production diffusion work.

Suitable for

• Portrait photography where softer skin texture and lower contrast are desired
• Videography aiming for a repeatable vintage or cinematic look
• Landscape and nature scenes with backlit highlights, e.g., sunlight through trees
• Low-light and forward-lit situations requiring stronger diffusion

How to use

Mount the 72 mm Hoya Mist Diffuser Black No1 onto a lens with a matching filter thread and compose your shot as usual. The filter diffuses bright points of light and softens contrast; for stronger diffusion effects increase exposure compensation or use longer focal lengths. Be mindful that the diffusion strength varies with focal length (stronger on telephoto, weaker on wide-angle), light source type, and camera settings such as shutter speed. Check the viewfinder and take test shots to confirm the effect on your chosen output medium.

Usage recommendations

Use No1 for forward-lit or low-light scenes where a stronger mist effect is desired; choose No0.5 for subtler softening in backlit or night scenes. Expect some variation in effect depending on light type and exposure—adjust exposure compensation and focal length to fine-tune the result.
