What is the purpose of a filter that is dyed in a specific manner?

The purpose of a filter that is dyed in a specific manner is to absorb light of certain colors. These filters are designed to selectively transmit certain wavelengths of light while blocking others. This allows photographers and videographers to manipulate the colors in their images, enhance contrast, or balance exposure. For example, a color filter can enhance the saturation of a specific color in a scene or reduce the intensity of colors that may otherwise dominate the image.

Such filters are commonly used in various applications, including photography, cinematography, and even in certain scientific measurements, where controlling the color spectrum is critical for achieving the desired visual outcome. Using a dyed filter effectively allows for greater creative control over the final image. Other potential purposes for filters, while valid in different contexts, do not relate specifically to the characteristic of being dyed and absorbing certain colors of light.
