The Tiffen 4 x 5.65" 1 Straw Hard Graduated filter helps to specifically add a warm golden yellow colouration to skies and other bright areas of an image whilst allowing a portion of the image to retain a neutral colouration.

The filter colouration is densest at the edge and tapers to the middle, with a sharp transition between the dense and clear areas. Colour density 1 provides less straw 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 5.65" / 101.6 x 143.5 mm.

The transition line of a filter in horizontal orientation is parallel to the long side of the filter.

Provides a warm golden yellow colouration to selected 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 colour of the density.
