Physically based renderers produce high quality images with high dynamic range (HDR) values. Therefore, these images need to be tone mapped in order to be displayed on low dy-namic range (LDR) displays. A typical approach is to blindly apply tone mapping operators without taking advantage of the extra information that comes for free from the modeling pro-cess for creating a 3D scene. In this paper, we propose a novel pipeline for tone mapping high dynamic range (HDR) images which are generated using physically based renderers. Our work exploits information of a 3D scene, such as geometry, materials, luminaries, etc. This allows to limit the assump-tions that are typically made during the tone mapping step. As consequence of this, we will show improvements in term of quality while keeping the entire process straightforward.
