Are the photos taken by photographers with digital cameras RGB or CMYK?

Digital cameras take "full color images"-only "shape" and "color" can be found by "light". The so-called "various colors" are obtained by human eyes and must be understood from the colors of objects and light sources. All colors of objects should have "light (line)". The illuminance of light determines the visibility, and the color of light also affects the color of objects. Imaging of cameras, projectors, movies, televisions, etc. Is all the image colors of light. The image of the image reflects that strong light is "white" with brightness, and "dark" such as black and night is dull or weak light. CMYK is the mixing proportion of color pigments in printing, but it is a mode in digital application. "K" stands for black, that is, darkness, such as the proportion of pigments used in printing. In order to correct light (light source), scientists decided to use RGB light source color to correct and explain the color of light to correspond to CMY number. In fact, RGBYMC is the color of light source that our human eyes can see; Physicists apply colorful rainbows-red, orange, yellow, green, blue, indigo and purple-to optics. Therefore, in optics, human vision is applied and it is full color. For the calibration of digital software, there is a so-called RGB mode or CMYK mode.
