The inventive method makes it possible to extract raw data from a photographic image and consists in determining for each pixel the combination V0[C,L] of image colour components, in calculating for each pixel a VN+1[C,L] value, in iterating from said calculation a predetermined number of times, afterwards in taking into account the values of a final VNfinal[C,L] image at each pixel, in calculating for each pixel the difference D [C, L] = VNfinal [C, L] - Vo [C, L], in calculating context data of noise Vs, in correcting raw data D [C, L] with the aid of context data Vs, in calculating a corrected I*[C, L] data taking into account D*[C, L] and in representing extracted data at a desired angle. ® KIPO & WIPO 2007
