Overview

The Cokin P727 Yellow CC40Y Color Correction Filter is designed to add a controlled yellow-warm shift to your images, making it a practical solution for counteracting blue or cool color casts produced by overcast skies, electronic flash, or daylight-balanced lighting in shaded environments. With a density of 0.40, it applies a moderate correction that is strong enough to be clearly visible in the final image while still looking natural — a useful middle ground for photographers who need reliable color adjustment without resorting to heavy post-processing.

Measuring 84mm × 84mm, this square filter is built for the Cokin M (P) Series holder system, one of the most widely adopted modular filter platforms available. This means it can be paired with a broad range of adapter rings to fit virtually any lens diameter, and it can be stacked alongside other P-series filters for combined effects. Whether you are shooting on color-negative film where in-camera filtration is essential, or on a digital body where you prefer to get color balance right at capture, the P727 provides a tangible optical correction that reduces the need for extensive white-balance editing afterward.
