Detailed Description

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 [62] .

For more information see [51] .
