This study, ordered by l'Agence photographique de la reunion des Musees Nationaux tries to answer the question: how to commercialize digital files instead of slides? We have chosen to analyze only the solutions available on the market except all the scanner's solution, images writers developed by the CNRS or any other research institutes. Generally, they are different from all the standards on the market of graphic arts. With this study, we want to stay compatible with the equipment used by the engravers who work with publishers. For that reason, we have divided this study in four parts:-Restoration of existing images-Digitalization of the stocks-Digital photography-Restitution of images, divided in three parts:-output on slide-output on imagesetter-printing (with a printer)To make it clearer and more efficient, we have made all the tests on the same 5 documents; 4 paintings and a small box for jewels. The pictures of three of the 4 paintings were more or less color damaged. With the fourth one, we had to suppress the brilliancy on the edges of the cracks.
