The Tiffen 4 x 5.65" Blue 4 Hard Edge Graduated filter is a hard-edge graduated colour filter that adds a bluish colour to the image, giving a cooling effect to your photographs. The graduated filter design maintains a neutral part of the image, which provides a more realistic appearance whilst allowing the sky or other bright areas to take on the density colour. Density 4 offers less blue tint than the density 5 filter, but more than density 3.

Tiffen filters are 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. This filter measures 4 x 5.65" / 101.6 x 143.5 mm and has a horizontal orientation; which means that the filter transition line is parallel to the long side of the filter.


- Blue tint gives a cooling effect to part of the image.
