48) Emphasis by Contrast (size)

When there is much to look at in a painting, contrasting sizes can identify a focal point, and draw emphasis on that object.

Since the man dressed in brown in front of the table seems a great deal smaller than the rest of the men and objects in the painting, the smaller man is emphasized.  There is even a value contrast even further emphasizing him as he is wearing a dark color as opposed to all of the white and lighter colors throughout the rest of the painting.
