The use of shadow is important for conveying lots of different things... mood of a person, setting or simply for dramatic effect. I am wondering specifically, in a close up shot of a face in the classic 3/4 position, what is the difference if the face is in shadow in the foreground versus on the background side?
For this assume the only difference in the drawing is the placement of shadow, the position expression and amount or surface covered in shadow are the same. The only difference is shadow on the side facing the viewer versus the side away from the viewer.
Here is my poorly drawn example of what i am thinking in my head. I tried to draw a neutral expression but they both kinda look upset... so try not to base the answer on the facial expression, just shadow placement:
What are the thematic/mood differences when the Audience views the picture?
