Color Filter A color filter is an optical accessory used in photography to selectively modify the colors of light passing through a lens. Color filters are made of transparent materials, such as glass or resin, that are coated with specific dyes or pigments to absorb certain wavelengths of light while allowing others to pass through. Color filters are commonly used to enhance contrast, correct color balance, and create artistic effects in photographs. For example, a red filter can darken blue skies and enhance contrast in landscape photography, while a warming filter can add warmth to images captured in cool lighting conditions. Color filters are available in various shapes, sizes, and colors to suit different creative and technical requirements. |
