The Tiffen 4 x 4" 2 Tropic Blue Soft Edge Graduated filter allows you to specifically add a cool blue-green colouration to skies and other bright areas of an image whilst allowing a portion of the image to retain a neutral colour. The filter's colouration is densest at the edge and fades towards the middle, with a smooth transition between the dense and clear areas. Colour density 2 provides less tropical blue colouration than density 3, but more than the density 1 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:

- Provides a deep blue-green colouration to certain areas of the image.
- The graduated filter design keeps a portion of the image neutral, giving a more realistic appearance whilst allowing the sky or other bright areas to take on the density's colour.
