What does sensor nd mean?

The sensor ND is an optical accessory that provides effective light filtering for the lens. It controls the amount of light entering the lens, allowing photographers to capture high-quality photos in a wide range of lighting conditions. ND filters can prevent overexposure and blur, allowing photographers to shoot with different exposure times, apertures and sensitivities to achieve more creative works.

Common types of sensor ND include linear and nonlinear ND. Linear ND provides the same light reduction effect at all optical density values, which means that its light reduction ratio is fixed, while linear ND can provide a light reduction ratio that can be customized according to different needs. This flexibility means that nonlinear ND can be effectively applied to a variety of photographic styles and environments, allowing for greater creativity and improved photo quality.

Because ND filters can capture clear, defined images by adjusting the exposure time, they are increasingly used in a wide range of photography fields. Sensor ND gives photographers more manual control without having to rely too much on post-processing. Whether outdoors or indoors, early morning or dusk, sensor ND can provide more creative shooting effects, and also plays a role in low-light environments that cannot be directly observed by human eyes, such as night street scenes, starry sky and aurora shooting, etc. .
