A man in a white shirt with headphones on his head is painting on a wall.
A class of preschoolers are fingerpainting on their desks.
The subject is either a (presumably adult) man or a group of preschool children. While both subjects are painting, the assumption is that the adult man is painting in a traditional manner (brush, roll, etc.), whereas the preschool children are explicitly fingerpainting. Finally, the man is painting a wall, whereas the children are painting on their desks.
