Reinhard Tone Mapping
Two parameters may be set for the Reinhard Tone Mapping: these are Saturation level and Brightness factor.
Saturation level is the input intensity level that will be brought back to 1. Setting this parameter to a high value preserves high-intensity lights.
Brightness factor enables the user to control brightness after processing. Setting this parameter to a high value leads to a light final image.
In order to use Sub-pixel correction, the corresponding box must be ticked. The Sub-pixel correction option limits aliasing phenomena in the HDR images.
The following images show the effect of Reinhard Tone Mapping for different saturation levels and brightness factors.
