UV - Film and a digital CCD are more sensitive to UV light than our eyes are. This often shows up in images shot from high altitudes and long distances especially over water. This filter will remove the UV light and more importantly protect your lens from moisture, scratches, and damage.
PL - Provides color and contrast enhancement. Reflected light often shows up as a whitish glare that washes out color in an image. A polarizing filter will correct this problem creating deep blue skies. It also removes glare from non-metallic surfaces such as windows and water.
FLD - Provides color correction when shooting under fluorescent lighting. It will remove the greenish tint from the image, providing pleasing skin tones and true to life color renditions.
