Zusammenfassung:	Method and apparatus for the observation of luminous phenomena, especially for the observation of luminous effects excelling in the ambient luminous intensity by their high luminous intensity. By the present invention the above aim is fulfilled by a method and a an apparatus by which light transmission is varied depending on the intensity of the light effect futhermore, variation of light transmission is effectuated by a signal higher than the final control signal. The decrease of light transmission is fast and is in conformity with the intensity of the luminous effect, and lack or failure of external supply do not affect safety of observation.
