Adaptive logarithmic mapping is a fast global tonemapping algorithm that scales the image in logarithmic domain. Since it's a global operator the same function is applied to all the pixels, it is controlled by the bias parameter. Optional saturation enhancement is possible as described in CITE: FL02 . For more information see CITE: DM03 .
