The Skylight and UV Haze filters absorb what type of light rays that cause the blue cast to objects in the distance?

1. Infrared

2. Ultraviolet

3. Visible

4. Gamma

The correct answer is: Ultraviolet

The Skylight and UV haze filters are specifically designed to absorb ultraviolet light, which can often cause a blue cast in photographs, particularly when capturing landscapes or distant scenes. This blue tint is especially noticeable in outdoor environments where UV rays can scatter, leading to a loss of detail and color fidelity in distant objects. By using these filters, photographers can reduce the effects of UV light on their images. This results in crisper contrasts and a more accurate representation of the natural colors in the scene. While infrared and gamma rays are not absorbed by these filters, it is the ultraviolet light that primarily contributes to the blue cast observed in images taken at greater distances. Thus, understanding the role of the Skylight and UV haze filters in managing light conditions is crucial for achieving clear and true-to-life photographs.
