VND & CPL Filters

$10USD

Why every serious operator carries a variable ND and a circular polariser. Stop reflections, hold shutter, and protect the cinematic look in any light.

Overview

Two filters live on the front of almost every serious operator's lens: a variable ND and a circular polariser. They solve different problems, and between them they let you protect the cinematic look in any light.

A variable ND (VND) is a darkening filter you can dial up or down. It cuts the light reaching the sensor without shifting colour, so you can hold a slow cinematic shutter and a wide aperture in bright daylight instead of being forced to stop down or speed the shutter up. A circular polariser (CPL) manages reflections and glare, rotate it to kill reflections off glass and water, deepen skies and saturate colour.

What's Inside
  • VND (Variable ND): a darkening filter that holds your 180° shutter and wide aperture in bright light, with no blown highlights
  • How it works: two stacked polarising elements you rotate to add or remove density (roughly 2–8 stops)
  • Watch the cross: pushing a VND to its extreme can show an X-shaped uneven patch, worst on wide lenses
  • CPL (Circular Polariser): cuts reflections off glass and water, deepens blue skies and boosts saturation
  • The CPL trade-off: it costs about 1–2 stops of light and works strongest at ~90° to the sun
  • On set: run a VND for exposure, and reach for a CPL when reflections or sky are the problem
