The Tiffen 4 x 4" 3 Cyan Hard-Edge Graduated filter allows you to specifically add a vivid cyan colouration to skies and other bright areas of an image whilst allowing a portion of the image to retain a neutral colour. The filter colouration is densest at the edge and fades to clear in the middle, with a sharp transition between the dense and clear areas. The colour density 3 provides less cyan colouration than density 4, but more than the density 2 filter.

This filter is manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and polishing it flat to a tolerance of 1/10,000th of an inch. It measures 4 x 4" / 101.6 x 101.6 mm.


Features:

- Adds vivid cyan colouration to specific areas of the image.
- The graduated filter design maintains a portion of the image neutral, giving a more realistic appearance whilst allowing the sky or other bright areas to take on the density colour.
