Control the Okko Pro 55mm ND Filter - 10 Stops is the amount of light in your image so you can do longer exposures during the day. Shoot in bright light without overexposing your images. Use slower shutter speeds to create dramatic effects that emphasise movement.
Videographers use the Pro ND in bright conditions for more consistent light and colour. Minimise your time spent in post-production by taking better images and videos with your camera.
