Abstract

Le dispositif d'adaptation 12 selon l'invention pour un flash électronique 11 comporte des bornes T1, T2, T3 reliées à un contact de synchronisation et à un contact de sortie de signal de réglage d éclairage d'un appareil de prise de vues photographiques comportant un mécanisme d'obturateur commandé electroniquement. Le dispositif d'adaptation 12 transforme un signal de réglage de lumière fourni par l'appareil de prise de vues photographiques à travers le contact de signal de réglage d'éclairage de cet appareil en un signal ayant une polarité et un niveau convenant pour le fonctionnement d'un circuit de commande de réglage d'éclairage (SCR1, SCR2, C3) d'un flash électronique.
