Cokin P163 Square Polacolor Yellow Polarizer Filter

The Cokin P163 Polacolor Yellow Polarizer is a square filter built for the Cokin P-Series (M-Series) holder system, one of the most widely used modular filter platforms in photography. Measuring 84mm x 84mm, it slots into the holder and can be rotated to vary the intensity of its signature yellow color cast. At one end of the rotation the image appears nearly neutral; at the other, a pronounced warm yellow tone washes across the scene. This variable control makes it a flexible tool for creative color work directly in-camera, without relying on post-processing.

Beyond the color effect, the P163 functions as a polarizer, helping to reduce glare and reflections from non-metallic surfaces such as water and glass. The filter introduces approximately 1-1/3 stops of exposure reduction, which is manageable in most daylight conditions but worth noting for lower-light situations. Because it is part of the Cokin P-Series, it can be stacked alongside other square filters in the same holder, opening up additional creative combinations for photographers who enjoy in-camera effects.
