ND filters for video: the essential outdoor accessory
ND filters let you keep cinematic settings in bright sun. Learn variable vs fixed ND, strengths and how to avoid color casts.
In bright daylight, the 180-degree rule and a wide aperture overexpose your footage. An ND filter reduces light so you can keep both.
Variable ND
Rotating the ring adjusts strength, usually from 2 to 8 stops. Fast and practical for run-and-gun shooting.
Fixed ND
Single strength, such as ND8 or ND64. Better image quality and no cross-polarization artifacts.
Avoid the X pattern
At maximum strength, cheap variable NDs create an X-shaped dark pattern, especially on wide lenses. Stay within the marked range.
Color casts
Lower-quality filters add magenta or green tints. Invest in reputable brands and correct white balance after attaching.
How strong
In Yucatán’s midday sun, at f/2 and 1/50 shutter, you may need 6 to 8 stops of ND.
Step-up rings
Buy filters for your largest lens thread and use step-up rings for smaller lenses.
Built-in alternatives
Some cinema cameras have internal ND; mirrorless cameras usually do not, so a filter is essential.
