Abstract
L'invention concerne les flashes pour appareils photographiques et, plus particulièrement, les flashes électroniques à tube-éclair. L'ensemble du flash électronique 5 qui peut être associé mécaniquement et électriquement à l'appareil photographique 1 comporte un filtre neutre absorbant 9, monté de façon coulissable, pour, lorsqu'il est placé, par la manoeuvre d'un levier solidaire 10, devant le tube-éclair 6, absorber une partie de l'intensité lumineuse émise par ce tube-éclair. On évite ainsi une surexposition du film due à l'intensité lumineuse émise par le tube-éclair non filtré lorsque le sujet photographié est relativement très rapproché par rapport à l'objectif.
