Figure 12. We stressed our approach by applying a strong range compression coupled with a large detail increase (a = 0.25, b = 0, s = log( 2. 5)).

The results are dominated by local contrast and are reminiscent of the popular, exaggerated “HDR look” but without the unsightly halos associated with it. In terms of image quality, our results remain artifact-free in most cases. We explore further parameter variations in the supplemental material.

Figure 13. We compare exaggerated, tone-mapped renditions of an HDR image. The wavelet-based method by Li et al. 21 is best suited for neutral renditions and generates halos when one increases the level of detail (a). The multiscale method by Farbman et al. 11 performs better and produces satisfying results for intermediate levels of detail (b), but halos and edge artifacts sometimes appear for a larger increase, as in this image for instance; see the edge of the white square on the blue book cover and the edge of the open book (c). In comparison, our approach achieves highly detailed renditions without artifacts (d). These results as well as many others may be better seen in the supplemental material.
