FAQs

What does an ND filter do?

It reduces the amount of light entering the lens so you can use slower shutter speeds (e.g. long exposure) or wider apertures in bright conditions without overexposing.

What strength ND filter do I need?

ND8 (3 stops) for portraits in sun; ND64–ND1000 (6–10 stops) for long exposures like smooth water. Variable ND (e.g. ND2–ND400) covers a range but can introduce colour cast.

Are variable ND filters any good?

Yes for convenience, but quality varies. Cheap variable NDs often have colour cast or uneven exposure. Mid-range options from K&F, Hoya, or B+W are more reliable.
