Abstract
In a photographic camera, a neutral density or other light reducing filter in the viewfinder obscures details of a subject viewed through the viewfinder in low light to provide a warning that ambient light is insufficient for a proper daylight exposure. The filter has little or no light reducing capability at a central portion and along a peripheral portion to serve as aiming and framing features, respectively.
