Abstract

L'invention a pour objet un perfectionnement apporté au dispositif photographique comprenant une pluralité de lampes à éclair coplanaires faisant l'objet du brevet principal. La présente invention a pour but d'éviter l'effet dit << des yeux rouges >> lors de la prise de vue de personnages. Selon l'invention, le circuit électrique est réalisé de telle façon que la mise à feu des lampes soit effectuée alternativement sur les deux rangées à partir de la lampe la plus basse jusqu'à la lampe la plus haute du groupe supérieur des lampes du dispositif. Application : lampes à éclair.
