Abstract

A. PROCEDE ET DISPOSITIF POUR DETERMINER LE GENRE DE FILMS EN COULEURS A SUBSTANCES CHROMOGENES DIFFERENTES, POUR TENIR COMPTE DE LEURS PROPRIETES LORS DE LA DETERMINATION DES QUANTITES DE LUMIERE DE TIRAGE POUR LES DIFFERENTES COULEURS PENDANT L'EXECUTION DES EPREUVES. B. AVANT LE DEVELOPPEMENT, ON REALISE PAR VOIE OPTIQUE OU PHOTOGRAPHIQUE, EN UN EMPLACEMENT DU FILM QUI N'A PAS ETE EXPOSE, DES REPERES 1C, 1D, 1E D'UNE COMPOSITION CHROMATIQUE PREDETERMINEE ET ON DETERMINE, APRES LE DEVELOPPEMENT, LE GENRE DE FILM PAR COMPARAISON DE LA TRANSMISSION SPECTRALE AU NIVEAU DES REPERES AVEC LES VALEURS DE LA TRANSMISSION DES DIFFERENTS GENRES DE FILMS. C. APPLICATION AUX TIREUSES POUR EPREUVES EN COULEURS.
