Lens filters guide: UV, polarizer, ND and more
Filters create effects software cannot replicate. Learn which filters are worth carrying and how to choose quality filters.
Filters sit in front of the lens to modify light. Some are essential; others are optional.
UV and protective filters
Modern sensors do not need UV filtering. A clear protective filter guards the front element from sand, salt and scratches, but cheap ones reduce image quality.
Circular polarizer
Cuts reflections, deepens blue skies and saturates foliage. Essential for landscapes, beaches, cenotes and real estate exteriors.
Neutral density (ND)
Reduces light for long exposures and video in daylight. Variable NDs are convenient for video; fixed NDs give better quality.
Graduated ND
Darkens the sky while leaving the foreground untouched, balancing sunsets.
Black mist and diffusion
Softens highlights and contrast for a cinematic, dreamy look in video and portraits.
Screw-in vs square systems
Screw-in filters are compact. Square systems are flexible for landscape photographers using several lenses.
Buy quality
Multi-coated glass from reputable brands prevents color casts and loss of sharpness.
