PolarPro QuartzLine 77mm ND100K Neutral Density Filter

PolarPro 77mm ND100K QuartzLine Solid Neutral Density 4.5 Filter

This filter offers a 32,000x filter factor, providing a 15-stop exposure reduction. Its 4.5 density darkens the entire image, enabling photography with a wider aperture or slower shutter speed than normally possible. This allows for greater control over depth of field and the ability to convey motion more effectively.

Usage

Neutral density filters like this one do not affect image coloration, making them ideal for use in combination with other filters. By reducing light exposure, photographers can achieve creative effects such as motion blur or shallow depth of field in bright conditions.
