In photography creation, how to skillfully use aperture size, shutter speed and white balance setting technology to create the artistic beauty of photographic images?

I think the aperture depends on the environment at that time, and the shutter speed is slow. As for the white balance, if you want to pursue artistic beauty, setting it in outdoor mode will have a yellowing effect (I think it is retro beauty), and setting it in indoor mode will have a blue tone.

If it is automatic adjustment, the image will be slightly red or blue when the external conditions exceed the automatic adjustment function of white balance; Even if there are more than 1 light sources in the automatic white balance adjustment function, the automatic white balance adjustment may not work properly. In this case, manual mode is needed to adjust the white balance. Before manual adjustment, you need to find a white reference object, such as white paper. Some DVs have a white lens cover, and the white balance can be adjusted as long as the white lens cover is covered. The operation process is roughly as follows: adjust the zoom lens of the camera to the wide-angle end, and cover the lens tightly with a white lens cover (or white paper); Adjust the white balance to the manual position, aim the lens at the clear sky, be careful not to directly face the sun, and zoom in until the whole screen turns white; Press the white balance adjustment button until the manual white balance sign in the viewfinder stops flashing (different machines have different representations), and then the manual white balance adjustment is completed.
