The Tiffen 4 x 4" 1 Antique Suede Solid Colour Filter adds a brown-green colouration across the entire image as well as a subtle warming effect. The solid colour design makes this filter particularly suitable for pairing with other filters to achieve increased control over image appearance. The colour density 1 offers less antique suede 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 flat to a tolerance of 1/10,000th of an inch. It measures 4 x 4" / 101.6 x 101.6 mm.
