Polarizer – Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens.

They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast.

The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

Soft Mist Black – The Soft Mist Black creates moderate image softening and modest-to-strong highlight flare, but without as much of a lightening effect in the shadow areas.

Graduated Neutral Density – Often it is necessary or desirable to balance the light intensity in one part of a scene with another. This is especially true in situations where you don’t have total light control, as in bright contrasty landscapes.

Exposing for the foreground will produce a washed-out, over-exposed sky while exposing for the sky will leave the foreground dark and under-exposed.

Graduated Neutral Density filters are part clear, part neutral density. They allow the transition to be blended into the scene, often imperceptibly.

Graduated Blue and Graduated Orange – Often it is necessary or desirable to balance the light intensity in one part of a scene with another.

This is especially true in situations where you don’t have total light control, as in bright contrasty landscapes. Sometimes it is also desireable to add color to part of the photograph. For example, to add blue to only the sky.
