1. A method to selectively and interactively fine-tune the tone-mapping of an image, the input image having a large dynamic range and the output image being adjusted for display on a low dynamic range display our output, comprising the steps of: a) calculating at least one first matrix, where each matrix entry is calculated as a function of the brightness within a corresponding area within the high dynamic range input image; b) calculating at least one second matrix, where each matrix entry is calculated as a function of the high dynamic range input image and of a user input data; c) calculating a third matrix as a function of the first matrix and the second matrix; and d) calculating a tone-mapped image as a function of the high dynamic range input image and the third matrix.
