Description

The Lee Filter Roll 281 3/4 C.T. Blue is a professional colour correction filter designed to increase the colour temperature of tungsten lighting and create a cooler, daylight-balanced look. Lighting technicians and cinematographers commonly use this gel to convert warm tungsten sources toward daylight tones. As a result, it helps achieve balanced colour when mixing tungsten lights with daylight or electronic flash.

This three-quarter CT Blue filter provides strong cooling correction without being as intense as a full CTB filter. Moreover, it shifts tungsten light from approximately 3200K toward around 5000K, producing a cooler and more natural daylight appearance. Consequently, it is widely used in film production, television, theatre, and photography where precise colour temperature control is required.

Supplied in a continuous roll format, the gel can easily be cut to the desired size for frames, barn doors, softboxes, or custom lighting modifiers. Therefore, it offers flexible lighting control for both studio and location environments. In addition, the durable polyester material withstands the heat generated by high-output lighting fixtures while maintaining consistent colour performance.
