What is a gray filter?
Gray filters, or neutral density (ND) filters, are homogeneously darkened over the entire filter area. Depending on the degree of density, there are lighter and darker gray filters. They reduce the amount of light that passes through the lens onto the sensor without changing colors or contrasts 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 Grey Filter, the result would be a considerably overexposed image.
- Soft smear or flow effects of moving water or passing clouds.
- Busy places with lots of people or busy streets can be made deserted by 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 portion of the light and you don't have to rely on compensating via camera settings (such as aperture, time or ISO).
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 holder. The precise workmanship meets the highest standards. Precise measuring procedures and strict quality control ensure the consistent high-end quality of our filters.
