SIRUI RGND8 (0.9) Rectangular Reverse Graduated ND Filter 100x150mm (3 Stops)

SIRUI RGND8 (0.9) Rectangular Reverse Gray Gradient Filter 100x150mm (3 Stops)

Impressive shots with balanced exposure throughout the entire image

A reverse gradient filter is perfect for subjects with a bright center and a clearly defined horizon (e.g., sunsets or sunrises). The result is stunning images with correctly exposed bright and dark areas.

What are SIRUI REVERSE Gray Gradient Filters?
SIRUI Reverse Gray Gradient Filters feature a hard gray gradient toward the center and a soft gradient toward the top edge of the filter. Depending on the density level, the filter gradients range from lighter to darker. This gray gradient darkens the tinted part of the filter over the subject. The high-quality SIRUI rectangular filters are made from German Schott B270® glass and come in a padded case for optimal protection.

SIRUI rectangular filters can be ideally combined to achieve the desired effect.

Material and Craftsmanship
The high quality of SIRUI filters starts with the material: they are made from Schott glass manufactured in Germany. The glass is fire-polished to ensure a perfect optical surface. This process also makes the glass extremely robust and durable. Rounded corners and polished edges make the filter glass more resistant to breakage. The filter also fits more easily into the holder. The precise manufacturing of SIRUI filters meets the highest standards. Exact measurement methods and strict quality control ensure consistent high-end quality of our filters.
