Impressive shots with harmonious exposure throughout the image
A reverse graduated filter is perfect for subjects with a bright center and a well-defined horizon (e.g. sunsets or sunrises). The result is stunning images with correctly exposed bright and dark areas.
What are SIRUI Grey Gradient REVERSE Filters?
SIRUI Reverse Graduated Gray Filters feature a hard gray gradient towards the center and a soft gradient towards the top of the filter. Depending on the density level, the filter gradients are lighter and darker. Due to this gray gradient, the tinted part of the filter darkens the subject. The high quality SIRUI rectangular filters are made of German Schott glass B270® and are delivered in a padded bag for optimal protection.
SIRUI rectangular filters can be ideally combined to achieve the desired goal.
Material and workmanship
The high quality of SIRUI filters starts with the material: they are made of Schott glass manufactured in Germany. The glass is fire-polished, which ensures a perfect optical surface. This process also makes the glass extremely robust and resistant. Rounded corners and polished edges make the filter glass more break-proof. This also makes it easier to insert the filter into the mount. The precise workmanship of SIRUI filters meets the highest standards. Precise measuring procedures and strict quality control ensure the consistent high-end quality of our filters.
