Neutral Density replacement packs of 5 or 10 filters allow the active Hero3+/Hero4 user to use and abuse their favorite filters without the need to repurchase a full kit. This kit includes replacement Neutral Density Filters in either 0.6, 0.9 or 1.2. These filters combat the rolling shutter effect caused by shaking or movement of the camera and the extremely short shutter speed of the Hero3+/Hero4 camera. Please note these filters will only work with the Formatt-Hitech Hero3+/Hero4 holder, which can be purchased separately.
Number of Filters:
These filters and holders are only way for GoPro users to use Formatt-Hitech’s professional quality and award winning filters. The holder is lightweight, unobtrusive, extremely durable, plus easy to install and remove using a single thumbscrew. Filters are made from the highest quality optical resin and significantly increase the image quality on GoPro Hero3+/Hero4 cameras by removing rolling shutter distortion, correcting color balance, adding polarization and increasing lens protection.
The holder system is designed to attach to the housing of the GoPro camera and two size options are available; Hero 3 (Wrist & Dive Housing) and Hero 3+/4. (Standard & Blackout housing).
These filters are designed specifically to:
・Eliminate the rolling shutter effect
・Create a cinematic look
・Add lens protection
・Add versatility to your shooting
Rolling Shutter Effect
The rolling shutter effect is caused by the extremely short shutter speed of the GoPro Hero3+/Hero4 camera combined with shaking or movement of the camera. The result is video that appears to jiggle like jello. Using a neutral density filter lengthens the exposure time sufficiently to eliminate the effect and significantly increase the video quality.
Achieving a Cinematic Look
The same neutral density filter that is used to eliminate the rolling shutter effect also lengthens the exposure time, creating a slight blurring in fast moving objects. This slight blurring replicates the look of 24fps cinema cameras and is more natural and pleasing to the human eye than video that appears overly sharp.
Formatt-Hitech’s resin filters are ultra flat, have excellent contrast and are completely transparent to the visible light spectrum. Formatt-Hitech’s resin has the highest scratch resistance of any non-glass optical material and it’s resistant to most solvents, chemicals, aging and material fatigue. Because of the ruggedness, light weight and portability, resin filters are a great choice for photographers and HDSLR filmmakers. Resin filters are dyed using our exclusive Absorbing Cell Technology process.
