Product Details:
Film, As Well As Video, Often Exhibits A Greater Sensitivity To What Is To Us Invisible, Ultraviolet Light. This Is Most Often Outdoors, Especially At High Altitudes, Where The UV-absorbing Atmosphere Is Thinner; And Over Long Distances, Such As Marine Scenes. It Can Show Up As A Bluish Color Cast With Color Film, Or It Can Cause A Low-contrast Haze That Diminishes Details, Especially When Viewing Far-away Objects, In Either Color Or Black-and-white. Ultraviolet Filters Absorb UV Light Generally Without Affecting Light In The Visible Region. It Is Important To Distinguish Between UV-generated Haze And That Of Air-borne Particles, Such As Smog. The Latter Is Made Up Of Opaque Matter That Absorbs Visible Light As Well As UV, And Will Not Be Appreciably Removed By A UV Filter.The UV Protector Shields Lens From Dust, Moisture, Scratches, And Breakage.
