UV Light Reduction UV light can negatively affect images, creating a bluish cast on color film or a low-contrast haze on either color or black and white. These negative effects of UV light are particularly noticeable with outdoor photographs, especially when taken at high altitudes or over long distances. The UV protection filter helps absorb ultraviolet light, which in turn helps create clearer, more accurately vibrant photographs.

What is UV (ultraviolet) light? The visual spectrum—the light we see with our eyes—consists of the colors red, orange, yellow, green, blue, indigo and violet. Mix them together and you get “white” light. The electromagnetic wavelengths of light are measured in terms of nanometers (nm), with the visual spectrum residing in the 390 to 750nm portion of the electromagnetic bandwidth.
