Protect your camera lens from ultraviolet light. The ultraviolet filter prevents UV light from reaching the lens, helping increase clarity and reduce haze. As a result, your photos look crystal clear even in mountainous and coastal areas, where ultraviolet light is particularly strong. The circular polarizer, meanwhile, is essential for outdoor photography, as it deepens the intensity of blue skies and reduces or eliminates glare. (Note that the circular polarizer is designed expressly for autofocus cameras.) Finally, the kit offers an exclusive color-warming filter that improves the color of all skin tones. Ideal for portraits, the color-warming filter absorbs the blue cast often caused by electronic flashes or outdoor shade, adding warmth to pale, washed-out flesh tones. This bundle kit is a great starter package for a beginning photographer, instructional use or an expert in photography.
