We have described a method for mapping calculated luminance values to values appropriate for displaying. Varying the contrast and aperture, images with the appropriate atmosphere can be displayed without knowing the luminances in absolute units. Also, for research purposes, some interesting parts of the images can be shown with lots of details by setting a small contrast and an appropriate aperture value. The introduced methods can save us additional renderings in most cases, and they reduce the time needed to produce the final image that way. Results strongly depend on the user settings, so this is a completely subjective method. Images mapped using this method are shown in the results chapter, color plates 2, 3, and 4.
