The colour density 1 provides less pronounced tobacco 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 6.6 x 6.6" / 167.6 x 167.6 mm. - The tobacco colour filter provides a warming effect to your images and adds a yellowish-brown colouration. - Solid colour filters apply density evenly across the entire image plane to achieve a smooth and creative effect.
