Radiant white clouds against a deep blue sky or the deep colors of fall foliage don't happen by chance. B+W polarizing filters (polarizers for short) augment the purity of the intrinsic colors and increase color saturation and are among the most important filters for analog and digital photography.
The maximum polarization effect is achieved in landscape photography when shooting at an angle of 90° to the sun. For an even effect in the picture, and because of uneven skylight polarization, your focal length should not be less than 28 mm in 35 mm format.
Generally speaking, with the help of a properly oriented polarizer, reflections can be completely suppressed in an ideal situation. Here, the ideal situation means that the lighting and shooting angles are almost the same and correspond to the angle of maximum polarization, usually 30° to 40°.
