Abstract

L'invention concerne une carte de référence destinée à être utilisée comme objet de référence en matière de réflexion lumineuse et d'équilibre chromatique en photographie, laquelle carte de référence a une couleur grise neutre et réfléchit une quantité prédéterminée de lumière. Ladite carte est caractérisée en ce que le dos de la carte de référence est pourvu d'un adhésif détachable et en ce qu'un certain nombre de cartes de référence sont assemblées sous la forme d'un bloc (1), sur une feuille (8) ou fixé sur une bande (7) stockée, en position roulée, de manière que les cartes de référence se protègent mutuellement de la lumière. L'invention concerne également un procédé de fabrication de ladite carte de référence, la couleur en question de la carte étant appliquée par pulvérisation ou peinture, de façon que la carte soit enduite d'un revêtement opaque.
