Polarizer Uses

  • Darken blue skies and enhance clouds
  • Remove reflections from water and glass
  • Increase color saturation in foliage
  • See through water surfaces
  • Reduce glare on wet or shiny surfaces
  • Cut haze in landscape photography

Tips

  • Rotate the filter while looking through viewfinder
  • Avoid ultra-wide lenses (uneven polarization)
  • Remove when shooting rainbows
  • Use CPL (circular) for autofocus cameras
  • Effect varies with filter rotation angle
