Ask the photographer to answer how to get the effect of the following pictures.

The first picture: The sun has stars, so the aperture is above F8.

The second picture: Eggbeater+steel velvet, the rope is tied to the hand and ignited. It will have this effect after exposure for about 30 seconds.

The third picture: The blue desert has nothing to do with the camera settings.

The parameters of the camera are not omnipotent, not to say that all scenes can be used, so the camera will have a metering system. Whether a photo is taken well depends on the correct exposure, that is, the combination of aperture, shutter and ISO, as well as post-processing. No post-photos are just like travel photos. The above three photos are all post-processed, including the blue desert.
