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
