Formatt 5X5 Rectangular Linear Polariser Filter
Polarisers
The linear polariser is the standard polarizing filter, and is an essential outside all-purpose filter. It deepens skies and minimizes reflections.
This filter is typically rotated to achieve the required effect; for this purpose you should ensure that your matte box has at least one rotating filter tray, and make sure when purchasing circular filters that you buy a polariser with a rotating ring.
