Abstract
This paper proposes several techniques that enable to display high
dynamic range pictures (created by a global illumination rendering
program, for instance) on a low dynamic range device. The methods
described here are based on some basic knowledge about human vision
and are intended to provide "realistic looking" images on the
visualization device, even with critical lighting conditions in the
rendered scene. The main features of the new techniques are speed
(only a handful of floating point operations per pixel are needed) and
simplicity (only one single parameter, which can be empirically
evaluated has to be provided by the user). The goal of this paper is
not to propose a psychovisual or neurological model for subjective
perception, but only to described some experimental results and
propose some possible research directions.
