A tone mapping algorithm for displaying high contrast scenes designed on the basis of the results of experimental using human subjects. evaluation of several existing tone mapping revealed that the most ``natural'' appearance was by the presence in the output image of detailed features often made visible by limiting contrast by properly reproducing brightness. Taking these results account, we developed a system to produce images close to ideal preference point for high dynamic range input image data. the algorithms that we tested, only the Retinex algorithm was of retrieving detailed scene features hidden in high luminance areas still preserving a good contrast level. paper presents changes made to Retinex algorithm for processing dynamic range images, and a further integration of the Retinex specialized tone mapping algorithms that enables the production images that appear as similar as possible to the viewer's of actual scenes.
