Methods and tools to evaluate the performance of tone mapping algorithms are needed. Some experiments have recently been presented involving human observers. In this paper, we propose method not relying on human scoring. Wellilluminated reference pictures of challenging scenes are captured and used as references. Low-quality shots of the same scenes are enhanced using some tone mapping algorithms and the outcome is compared to the reference images using a standard colour distance measure. The results clearly favour the more sophisticated local methods.Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Viewing Algorithms
