A method of simulation of a recording support rendering called target
rendering is provided. The method includes the following successive
steps: a) the digitization of images (12) captured on a first support
(10) and at least one sensitometry control (14) recorded on the same
support, so as to obtain initial digital codes for a set of pixels taken
in the images and the sensitometry control, b) the establishment, from
the digital codes of the sensitometry control (26), of an initial
sensitometry relationship (26) for the first digital support, the initial
sensitometry relationship (26) linking the digital codes to the support's
light exposure values, c) the establishment, from one target sensitometry
relationship (28), corresponding to the target rendering, of new digital
codes for a number of image pixels, the new digital codes being
established so that the new digital code and initial digital code of each
pixel are linked to the same exposure value, respectively by the target
sensitometry relationship (28) and the initial sensitometry relationship
(26).
