The Lee Filters 1/2 CTS 48"x25' Roll Gel Filter is designed to provide a moderate color temperature shift, converting light from tungsten (3200K) to a balanced daylight color temperature (around 4300K). This filter is ideal for situations where you need a slight warming effect without fully shifting to daylight. Commonly used in film, photography, stage, and broadcast lighting, the 1/2 CTS filter ensures a smooth transition from warmer tungsten lighting to a more neutral daylight tone, maintaining a natural and consistent color balance.
