Neutral Density Filters

ND filters attenuate light equally within the visible spectrum.  Ideal tool when thumb rule that exposure Time = 2xframe rate-1 is still too bright with given F-stop. Maintaining a low F-stop for gaining a small depth of field these filters are used for control of bright day exteriors. They, therefore, allow more widely opened apertures. 

Graduated neutral density filters are used to darken an overly bright part of a scene, like a sky, and lighten the foreground. They bring an overly bright part of a scene into the dynamic range of the sensor.

Our Rhodium FSND filter (Full Spectrum Neutral Density) attenuate light equally within the wavelength range from 350-1000nm including UV- and near IR-light. This is of particular importance to avoid IR light pollution resulting in unwanted purple and/or violet color artefacts in dark areas of the frame. Additionally, we attach a great emphasis on color consistency to allow easy color grading, all shots, filtered, or unfiltered can be graded in the same way. This is important specifically for the critical color standards of 4K, 6K, and 8K resolution cameras and the short turnaround times in today’s post-production processes.
