The Tiffen 4 x 4" 3 Tangerine Soft Edge graduated filter allows you to specifically add a pale warm orange colouration to skies and other bright areas of an image whilst allowing part of the image to remain colour neutral. The filter colouration is densest at the edge and fades towards clear in the middle, with a smooth transition between the density areas and the clear areas. The colour density 3 provides a more pronounced tangerine colouration than the density 2 filter.nnThis filter is manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it flat to a tolerance of 1/10,000th of an inch. It measures 4 x 4" / 101.6 x 101.6 mm.nnnFeatures:nn- Adds pale orange colouration to certain areas of the image.n- The graduated filter design maintains part of the image neutral, giving a more realistic appearance whilst allowing the sky or other bright areas to take on the colour of the density.nnnSpecifications:nn- Type: Tangerine colour graduated soft edgen- Size: 4 x 4" / 101.6 x 101.6 mm (0.2" / 4 mm thick)n- Density: 3n- Effect: Used to give photographs a spectacular coloured effectn- Construction: ColorCore glass
