Neutral Density Filters
  • Type: Filters
  • Diameter / Dimension: 5mm - 300mm
  • Filter Category: Neutral Density Filter

Neutral density filters attenuate light by a constant amount that is, to first order, independent of the wavelength. Gelatin ND filters are the cheapest but tend to have more fluctuation with wavelength and a narrower wavelength range than glass ND filters and metallic types. Gelatine ND filters work by absorption so care must be taken to avoid overheating which can lead to damage.
