What is a grey filter?
Gray filters, or neutral density filters (ND), are darkened homogeneously over the entire filter surface. Depending on the density, there are lighter and darker gray filters. They reduce the amount of light that hits the sensor through the lens without changing the colors or contrast in the image.

Why do you need a gray filter?
Filters are indispensable for long exposures during the day and open up countless creative possibilities. Without the use of the SIRUI gray filter, a significantly overexposed image would result.

• Soft wiping or flowing effects of moving water or passing clouds.
• Busy places with lots of people or busy streets can be made deserted using long exposures with a gray filter.
• For working with an open aperture to create a shallow depth of field. Large amounts of light are compensated for by the filter. It simply "swallows" a large part of the light and you do not have to compensate for it using the camera settings (such as aperture, time or ISO value).

material and workmanship
The high quality of the SIRUI filters starts with the material: they are made from Schott glass made in Germany. The glass is fire polished, which ensures a perfect optical surface. This process also makes the glass extremely robust and durable. Rounded corners and polished edges make the filter glass more shatterproof. This also makes it easier to insert the filter into the holder. The precise workmanship meets the highest standards. The most precise measuring procedures and strict quality control ensure the consistent high-end quality of our filters.
