In short, it is just using the layer mask, but it is quite excellent even if saying that its usage is the basis of the basic.




By the way, in the case of images like the one below, the method is also different, it seems that by separating the foreground person and the background and adjusting the contrast etc., the feeling that intense light is hitting the background . This seems to be easier than it looks.
