I am new to the forum and beginning to build a shadow box. A question about the shadow box: does any remaining opening in the roof need to be covered while using the shadow box? i.e. the light box is over top of the opening, and some boards to create shadows on the still life.
Also, in Mark's description of the studio setup, he shows one light on the ceiling at 35 degrees to the canvas. Should there only be one light in the room?
