A viewer looking through the red rectangle sees a ghost floating next to the table. The illusion is produced by a large piece of glass, acrylic glass or plastic film (green outline) situated at an angle between viewer and scene. The glass reflects a room hidden from the viewer (left), sometimes called a blue room, that is built as a mirror-image of the scene.
If the mirror-image room (left) is darkened, it does not reflect well in the glass. The empty room (top) is brightly lit, making it very visible to th
If the mirror-image room (left) is darkened, it does not reflect well in the glass. The empty room (top) is brightly lit, making it very visible to the viewer.

This is a photograph of a small part of an unbleached transmission hologram viewed through a microscope. The hologram recorded an image of a toy van and car. It is no more possible to discern the subject of the hologram from this pattern than it is to identify what music has been recorded by looking at a CD surface. The holographic information is recorded by the speckle pattern.
