NiSi Cinema Linear Polariser and Rotating CPL
There are two types of polariser, linear and circular. Their function is to reduce reflections on non-metallic surfaces in order to reveal the original colour and texture of an object. They can also help to increase the colour saturation beyond that of normal vision and the effects cannot be easily replicated in post-processing.
