Short title	One sign emits light through smoke; the other reflects incident light towards an observer.
Image title	Two panels. Left: a light-emitting exit sign produces its own light, which travels through smoke to an observer. Right: a separate luminaire sends incident light onto a reflective sign, and only the reflected part travels back through the smoke to the observer. The light path weakens as it crosses the smoke in both panels.
