A UV filter is a colourless photographic filter designed to absorb ultraviolet light, which can cause haze and reduce image clarity, especially when shooting black-and-white film. It helps produce sharper, cleaner images by minimising the effect of UV light on film or digital sensors.
Photographers use UV filters to protect lenses from dust, scratches, and moisture while improving image quality in outdoor and high-altitude conditions. Understanding the benefits of UV filters ensures clearer photographs with better contrast and detail in challenging lighting environments.
