Tiffen 43FLD 43mm FL-D Fluorescent Light Correction Filter

The Tiffen 43mm FL-D Fluorescent Light Correction Filter is a purpose-built optical accessory designed to counteract the characteristic green color cast that fluorescent lighting produces in photographs. Fluorescent tubes emit light with an uneven spectral distribution that skews heavily toward green, and the FL-D filter compensates by introducing a complementary magenta tint. The result is more accurate, natural-looking colors — particularly in skin tones — without the need for extensive post-processing. Built using Tiffen's ColorCore technology, the filter sandwiches the color-correcting material between two layers of optical glass, providing consistent color rendition across the entire surface of the filter.

At 43mm, this filter is sized for compact lenses and smaller-bodied cameras. It screws directly onto the front filter thread, making it easy to attach and remove as lighting conditions change. While modern digital cameras offer fluorescent white balance presets, the FL-D filter remains valuable for photographers who prefer optical correction at the point of capture, for those shooting video where consistent frame-to-frame color is essential, and especially for film photographers who cannot adjust white balance in post. Manufactured in the United States, the Tiffen 43FLD reflects the company's long-standing reputation for reliable, affordable photographic filters.
