The Tiffen 4 x 4" 3 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 part 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 smooth transition between the dense and clear areas. The colour density 3 provides more tropical blue colouration 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 to a tolerance of 1/10,000th of an inch. It measures 4 x 4" / 101.6 x 101.6 mm.


Features:

- Adds deep blue-green colouration to certain areas of the image.
- 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 density colour.
