Black mist filters of different levels gradually soften the highlights in the picture, and the transition between light and dark will also become softer. The larger the value, the stronger the softening effect. 

Black mist 1: The soft focus effect is the strongest and the haziness of the picture is the most obvious. It is recommended to use when the contrast between light and shadow is large, or the highlight range is small. Black mist 1/2: The soft focus effect is stronger and the image is more hazy. It is recommended to use if the contrast between light and shadow is large, or in an environment with large contrast between light and shadow. Black mist 1/4: The soft focus effect is relatively mild, the soft focus range is moderate, and it is quite versatile, also suitable for environments with little contrast between light and shadow. Black mist 1/8: The soft focus effect is the lightest, and sometimes it is not even obvious when there are few highlight areas. However, this gentlest soft focus also brings the greatest applicability, and the effect is very good when used in environments with various light ratios. 

In terms of imaging, the filter uses ultra-low reflection technology to significantly suppress ghosting effects; the filter frame uses high-grade brass frame, which is easy to install and disassemble; it has 36 layers of coating, which is hydrophobic, oleophobic, scratch-resistant and mildew-resistant.
