Tiffen 138mm 82A Light Balancing Round Filter

The Tiffen 138mm 82A Light Balancing Round Filter is a professional-grade optical filter designed for cinematographers and videographers who require precise in-camera color temperature adjustment. By adding approximately 200 Kelvin to the scene's color temperature, the 82A introduces a subtle cooling effect that corrects slightly warm lighting conditions — useful when shooting under mixed lighting or when you want to nudge the overall tone toward neutral without a dramatic shift. This level of fine-tuning can be difficult to replicate precisely with digital white balance alone, as optical filtration affects the light before it reaches the sensor, preserving highlight and shadow detail in a way that post-production color grading may not.

Built using Tiffen's proprietary ColorCore lamination process, the 82A delivers even, consistent color across the full 138mm surface without the edge-to-edge variation sometimes found in lesser filters. The 138mm round, unthreaded format is an industry standard for professional matte box systems, making it compatible with virtually any cinema-style rig. While the rise of digital color correction has reduced the necessity of optical color balancing filters for many workflows, the 82A remains a valued tool for professionals who prefer to get the color right in-camera — particularly in broadcast, documentary, and narrative production environments where consistent, repeatable results take priority.
