The colour density 2 provides less tangerine colouration than density 3, but more than the density 1 filter.nnThis filter is 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 6.6 x 6.6" / 167.6 x 167.6 mm.nnn- The tangerine colour filter brings warm, pale orange colouration to your images and reduces cooler tones.n- Solid colour filters apply the amount of density uniformly across the image plane to achieve a smooth, creative effect.nnnSpecificationsn
