How do professional photographers creatively use live light?

In this scene light photo taken by Hracha Amid, the light from the nearby window subtly shows the softness and smoothness of the child's skin and his reverie. The reflection of the walls and sheets makes the children's room like a holy and ethereal fairyland.

Real-time light coming through the window has always been the favorite light source for painters and photographers. FritzHenle knows that he doesn't need to do anything more, just find the angle he wants and press the shutter. The white sheets under the baby reflected the light on the faces of the two little girls, making the shadows appear sparse and soft.

Ernst Haas captured the main features of composer LgorStravinsky when conducting orchestral music. Except for a few parts that can outline the activities of the characters, all the other parts are black. We saw the main features of his face, including the contour light of his ears and head, so we could recognize the man. We saw his hands moving, so we could recognize his body outline. If a cartoonist wants to draw Stravinsky, shouldn't he choose these basic elements? Ernst Haas's way of using light here may be Picasso's way of using light, that is, only a few simple lines are used to sketch the image-that is, in order to describe the object, he only illuminates the absolutely important part and ignores the other parts. This is a good example of live lighting photography skills.
