What is a UV Filter?

A UV filter is a clear or lightly tinted filter placed in front of a camera lens to block ultraviolet (UV) light. Originally designed to prevent UV light from causing haziness in film photography, its application has evolved in the digital age.

• Color and Contrast Enhancement: In high-altitude or coastal environments, UV filters can sharpen color and contrast.
• Cost-Effectiveness: Replacing a UV filter is significantly cheaper than repairing or replacing a damaged lens.
