Look at your footage, now look at the Pro's... what is making their picture so sharp and vivid? You guessed it, a ND filter (plus the skills but we won't talk about that)! There are plenty of options to apply such a filter but our stick-on application makes it easy and lightweight! No need to deal with extra frames or cases. Filters allow you to slow down the shutter speed to capture that more "cinematic" feel. ND4 is the lighter option, ND8 is darker.
