Combining two distinct filter effects in one, the Tiffen 4 x 4" Ultra Circular Polarising Warming filter helps to reduce reflections and glare whilst adding an overall warm tone. The Ultra circular polarising effect offers deep, saturated, rich colours, and effectively eliminates haze and reflections from non-metallic surfaces. Complementing these effects, the incorporation of an 812 warming filter in the design adds a natural glow to skin tones and other subjects, making it particularly suitable for outdoor use in shade conditions where there is excessive blue cast.

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. It measures 4 x 4" / 101.6 x 101.6 mm and is compatible with certain filter holders or matte boxes.


Features:

- The Ultra circular polariser significantly reduces reflections and glare by filtering polarised light due to reflection on a non-metallic surface.
- Reduces haze in distant landscapes and offers more saturated and vivid colours.
- A circular polariser differs from a linear polariser as it allows full use of the camera's autofocus and auto-exposure functions.
- Strongest effect when used at 90° to the sun.
- The 812 warming filter effect brings an overall warm tone to the image and is ideal for working in conditions with pronounced blue cast.
