Abstract

L'invention est relative à la photographie. L'appareil, suivant l'invention, permet d'identifier la qualité de la lumière pour introduire automatiquement sur le faisceau de prise de vues un filtre correcteur approprié en fonction de la sensibilité spectrale du film et de la qualité de la lumière détectée. Pour ce faire on détermine le papillotement de la source au moyen d'une cellule 12 et d'un pont de diodes 26. Application à la correction automatique de la composition spectrale d'un faisceau lumineux.
