This 10 pack of 0.6 Neutral Density Filters for GoPro Hero3+ & Hero4 Cameras from Hitech is useful for slowing down the shutter speed of your GoPro in bright settings. This allows for a more blurred and cinematic image that will also improve the look of rolling shutter. Each filter measures 33 x 36 mm, is made of a high quality optical resin, and will easily fit into the Hitech GoPro Hero3+ & Hero4 filter holder.
These neutral density filters are rated at 0.6, equivalent to 2 stops of exposure reduction, creating a darkening of the entire image and allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
