Hitech 85mm Blue - CC05B - Color Compensating Resin Filter - for Cokin P

Some photographic situations require specific color corrections. For example, when shooting daylight film under fluorescent lighting, some magenta correction is needed in order to remove the greenish tint that would otherwise appear. The amount of color correction required is most accurately measured via a color temperature meter. Color Compensating filters are available in the three primary colors: Red, Green, and Blue; and in the three secondary colors: Cyan, Magenta, and Yellow. A typical designation for one of these filters is CC30M. The "CC" stands for Color Compensating. The "30" stands for a density of 0.30 and the "M" is for magenta.

Hitech resin filters are made from lightweight, optical resin. These particular Hitech filters measure 85 x 85mm and fit Hitech's 85mm filter holder. They will also fit the Cokin "P" series holder.

Hitech Color Compensating filters are available in the following increasing densities: 0.025(CC025), 0.05(CC05), 0.10(CC10), 0.15(CC15), 0.20(CC20), 0.30(CC30), 0.40(CC40), 0.50(CC50).
