Illuminated frames provide a simple mechanism for making a photographic print stand out, and even become the central point of a room. Custom-made frames containing low-voltage LED illumination are available. A normal print is inserted in the frame and back-lighting is provided by an illuminated translucent screen. The print then glows in a manner which makes it appear somewhere between a back-lit transparency and a front-lit print. The technique is effective in daylight but more prominent in artificial light. Frames are available in a range of sizes and are powered by either batteries or a connection via a low-voltage transformer to the mains supply. The LEDs have an extremely long life and the cost of running the illuminated frame is negligible. The manufacturers claim that their products are extremely safe and appropriate for use in children's rooms.
