Description

The Lee Filter Roll 203 Quarter C.T. Blue is a professional colour correction filter designed to cool tungsten lightingand bring it closer to daylight balance. Lighting technicians and cinematographers commonly use it to mix warm tungsten sources with cooler daylight or LED fixtures. As a result, it helps achieve consistent colour temperature across different lights in film, television, theatre, and photography setups.

This quarter CT Blue (C.T. Blue) filter causes a moderate cooling effect — less intense than a half or full CTB filter — making it ideal when only a gentle shift toward cooler colour temperature is required. This subtle adjustment enhances visual balance without dramatically altering the overall lighting mood.

Supplied in a continuous roll format, the gel can be cut to the size you need for frames, barn doors, softboxes, or custom lighting modifiers. Therefore, it offers flexible colour temperature control for both studio and location work. In addition, the professional polyester material provides stable performance and withstands heat from high‑output lighting fixtures.
