What is colour filter
1 answer
A color filter is a transparent material that absorbs certain colors of light and transmits others. It can be used in photography, cinematography, and other optical applications to alter or enhance the colors of an image. By placing a color filter in front of a light source or lens, certain wavelengths of light are blocked or intensified, resulting in a change in the overall color balance of the scene or subject. Color filters can be used creatively to create different moods, emphasize certain colors, or correct color imbalances in a photograph or video.
