Cokin

Cokin A139 A-Series FLD Graduated Fluorescent to Daylight Conversion Filter

SKU CH-NC8K-QD7FQ

A graduated filter that neutralises greenish fluorescent tones for natural daylight colour balance

  • Neutralises greenish fluorescent cast with FLD conversion
  • Graduated design balances mixed lighting smoothly
  • 2/3-stop density corrects colour without over-darkening
  • Cokin A-series build quality for reliable use
  • Compatible with A-series filter holders for quick fitting

Product Purpose

The Cokin A139 A-Series FLD Graduated Fluorescent to Daylight Conversion Filter neutralizes greenish color casts from fluorescent lighting. It is designed for photographers who need accurate color reproduction in environments such as offices, stations or restaurants where artificial light dominates.

Who Benefits

Photographers working under mixed lighting will appreciate the graduated effect that provides a smooth transition between corrected and uncorrected areas. This filter is not suited for shooters who require full-frame correction without a gradient or those needing stronger than a 2/3-stop adjustment.

Capacity and Headroom

The 2/3-stop density comfortably handles typical fluorescent-to-daylight conversion while preserving highlight detail. It runs out when lighting conditions demand a deeper correction or when a non-graduated filter is required for even illumination across the entire frame.

Highlights

  • Neutralises greenish fluorescent cast with FLD conversion
  • Graduated design balances mixed lighting smoothly
  • 2/3-stop density corrects colour without over-darkening
  • Cokin A-series build quality for reliable use
  • Compatible with A-series filter holders for quick fitting

Questions about this item

Which Cokin filter holder system is required to mount the A139 filter?

The A139 is an A-Series filter, so it fits the Cokin A-Series filter holder and adapter rings.

Will the graduated design affect exposure on the unfiltered half of the frame?

The clear portion adds no density, so exposure remains unchanged while the filtered half reduces fluorescent light by 2/3 stop.

How can I verify the filter is removing the green cast after I attach it?

Shoot a white or grey card under the same fluorescent lights; the image should render neutral without the typical green tint.
