heal.abstract	The present work deals with the problem of colorimetric fidelity of digitized colour slides representing fine al? paintings. This consists of a comparison between colour measurements provided by spectrophotometry on fourteen original colour samples, which are uniformly painted square-shaped patches and those taken on digitized colour slides of the same colour samples. Digital acquisition of slides were performed by a 3CCD detector and a combination of colour correction filters. The obtained R-cam, G(cam), and B-cam values were then corrected and transformed into X-cam, Y-cam, and Z(cam) values based on the CIE 1931 XYZ colorimetric system. The colour difference, Delta E-CMC, in the CMC uniform colour space is also calculated and found to be equal to seven, Delta E-CMC = 7, in average value, when colour compensating filters are used. This method is finally applied to four art works reproduced on different slides, and colour results were qualitatively compared as an indication to these resulting from Ostwald disk and saturation diagrams of previous research studies related to paintings that are created br the same artists. This comparison led to the same conclusions that were already proposed by the previous researchers. The results clearly demonstrate the contribution of the method to a computer-aided study of art works through image data banks that are realized by slides, taking into consideration, however, that this study consists of a first approach, offering a promising solution to the problem of colour accuracy of slides.
