Overview

The Tiffen 43FLB is a fluorescent light balancing filter designed to correct the unflattering green-magenta color shifts that fluorescent lighting introduces when shooting with tungsten-balanced film. By filtering out the problematic wavelengths, the FLB restores pleasing skin tones and accurate color rendition without requiring a flash, making it a practical solution for documentary, event, and indoor photography where fluorescent fixtures are the primary light source.

Built with Tiffen's optical glass and a sturdy metal mounting ring, the 43FLB maintains image quality while providing durable, reliable performance. The 43mm thread size is tailored for smaller lenses commonly found on compact cameras, rangefinders, and select mirrorless systems. For photographers still shooting tungsten film in mixed or fluorescent-dominated environments, this filter remains an essential tool for getting color right in-camera.
