What does photography include?

My photography experience believes that photography technology should at least include the following contents: first, the understanding of the camera and the proficiency in correct use (such as the use of aperture size, shutter speed, sensitivity and the proficiency in the selection of imaging pixels); The second is the understanding and application of light (such as the application of various light levels such as side light, backlight and front light, and the use of auxiliary light); The third is the understanding and application of photographic composition; The fourth is the sensitivity and ability to capture wonderful moments.
