The Tiffen 4 x 5.65" Color Graduated Sepia 3 filter is part of Tiffen's award-winning Color Graduated filter series and is one of the most widely used. It enhances reality by adding a touch of subtlety or drama to the image. This filter gives you the ability to add more “punch” to an otherwise ordinary scene. Tiffen graduated filters give you the control needed to create a scene rather than simply photograph it. Sepia filters give an “antique” look to your images. With graduated filters, it is often necessary or desirable to balance the light intensity of one part of the scene with another. This is particularly true in situations where you don't have complete control over lighting, such as in bright, contrasty landscapes. Sometimes it is also desirable to add colour to part of the photograph. For example, to add blue only to the sky. Tiffen Color Graduated filters are half-coloured, half-transparent, with a graduated transition to blend into the scene. They are available in a range of colours. The Soft or Hard label indicates the degree of colour graduation. Horizontal/Vertical indicates the direction of the graduation. Whether at Pro or Photo 1 level, Tiffen filters have always been the industry's first choice. Note: Tiffen Color Graduated Sepia filters are available in intensities from 1 to 3, with 3 having the most pronounced effect. - Add colourful excitement to a dull sky - Change the specific colour of a scene to create a desired special effect - Enhance existing colour or create subtle colour drama - Create a more balanced exposure in uneven lighting conditions ColorCore Technology - Tiffen filters are manufactured using ColorCore technology, a closely guarded proprietary process that involves permanently laminating the filter material between two pieces of optical glass that are polished flat to tolerances of one ten-thousandth of an inch, then mounted in precision metal rings - The ColorCore process allows Tiffen to control the colour and density of their filters, as well as the characteristics of special effects filters with precision far superior to typical mass-tinted filters, which typically exhibit colour and density variations Superior Quality - Major Hollywood film studios rely on Tiffen filters for their multi-million pound productions - Superior quality and design make Tiffen the overwhelming choice of filmmakers, professional photographers and even NASA - Tiffen has also received an Emmy from the Academy of Television Arts and Sciences for excellence in engineering Specifications
