What is a Neutral Density Filter?
Neutral density filters, or ND filters, are evenly darkened across the entire filter surface. Depending on the density level, there are lighter and darker ND filters. They reduce the amount of light reaching the sensor through the lens without altering colors or contrast in the image.

What is a Neutral Density Filter used for?
Filters are essential for long exposures during the day and open up countless creative possibilities. Without using the SIRUI ND filter, the image would be significantly overexposed.

• Soft smearing or flowing effects of moving water or passing clouds.
• Busy squares with many people or heavily trafficked streets can be made empty of people through long exposures with an ND filter.
• For working with a wide aperture to create shallow depth of field. Large light intake is compensated by the filter. It simply "absorbs" a large part of the light, so you don’t have to compensate through camera settings (such as aperture, shutter speed, or ISO).

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, ensuring a perfect optical surface. This process also makes the glass extremely robust and durable. Rounded corners and polished edges make the filter glass more break-resistant. The filter also fits better into the holder. The precise workmanship meets the highest standards. Exact measurement methods and strict quality control ensure consistent high-end quality of our filters.
