How do I backlight an image?
To be effective, Lithophanes require some type of backlight to define the image and bring it to life. Achieving the correct material thickness coupled with a proper backlight are two major factors that help create an impressive Lithophane.
Providing a backlight can be as simple as placing the Lithophane in a window or in front of room lighting or as complex as building a frame and adding low heat type lighting behind it.
