Värvifiltrit
Värvifiltrit refers to a color filter in Estonian. A color filter is an optical component that selectively transmits certain wavelengths of light while absorbing or reflecting others. These filters are used in a wide variety of applications to modify the color of light. In photography and videography, they are used to adjust the color balance of an image, enhance contrast, or create specific artistic effects. For example, a red filter can darken a blue sky in black and white photography, making clouds stand out more. In scientific instrumentation, color filters are crucial for spectral analysis, allowing researchers to isolate specific wavelengths for measurement. They are also employed in display technologies like LCD screens to produce a full spectrum of colors from white light. The material composition of a color filter determines its filtering properties. These can include dyed gelatin, colored glass, or thin-film coatings. The primary function remains consistent: to control the color of light that passes through it.
