Want to add a background scene that simulates both daylight and night lighting conditions? These unique backgrounds are printed on translucent material that allows you to use them two ways. When lit with conventional room lighting, they offer a photo-realistic background scene. To simulate a nighttime scene, simply mount the scene in a frame with a light box behind it (both sold separately) and the scene is magically transformed. The translucent base is printed with a pattern that allows bright light to shine through only in selected places such as through windows and on streetlights. The rest of the scene gets its depth fromthe remaining shadows.
