Abstract
A method of generating a representation of an image comprises scanning a film (2) carrying an image to which the film has been exposed to obtain signals (4,5,6) representing the color component content of the recorded image. During exposure of the image its appearance has been modified in accordance with a function characteristic of the film. The signals obtained are modified with a function (11,10,8) constituting the inverse of the film characteristic function to compensate.
