4a. Napa Valley: tone mapping

Dynamic range reduction of the image Napa Valley by means of eight different tone mapping algorithms: the Ward histogram adjustment [1], the logarithmic mapping proposed by Drago et al. [2], the Reinhard et al. photographic tone reproduction method [3], the Reinhard and Devlin algorithm based on a photoreceptor model [4], the Durand and Dorsey method based on the bilateral filter [5], the Ashikhmin spatially-variant operator [6], the gradient domain operator proposed by Fattal et al. [7] and our method.
