The four photographic rays refer to the four primary colors used in photography: red, blue, green, and yellow. These colors are important because they can be used to create a wide range of colors and tones when they are mixed together in different proportions.
In traditional photography, these four colors are used to create filters that are placed in front of the lens of the camera. Each filter allows certain wavelengths of light to pass through and block others, which affects the way that the scene is captured. For example, a red filter will allow red wavelengths of light to pass through and block other wavelengths, which can create a warm, reddish tone in the photograph.
In digital photography, the four primary colors are used in a different way. Instead of using filters, digital cameras use sensors that are sensitive to red, green, and blue light. These sensors capture the light that reflects off of the scene and converts it into digital data, which can then be processed by the camera's processor and used to create an image.
Overall, the four primary colors are important in photography because they allow photographers to control the way that light is captured and create a wide range of tones and colors in their images.
