To circumvent this, we propose an image-based method which adds perceptually plausible participating media effects to a single, clean high dynamic range image. We impose no prior requirements on the input image, and show that the underconstrained nature of the problem (where variables like depth or reflectance properties of the objects are obviously unknown) can be overcome with relatively little unskilled user input, similar to other image-editing techniques. We additionally validate the visual correctness of the results by means of psychophysical tests.Categories and Subject Descriptors (according to ACM CCS): I.3.4 [Computer Graphics]: Graphics Utilities
