Tone Mapping

The Tone Mapper, accessible from the Rendering > Render Setup… > Settings tab, enables various controls over the appearance of your scene. These can be used during rendering without interrupting progress.

• Enable Tone Mapping: toggles the Tone Mapper on or off. When enabled, the Tone Mapper makes interactive visual adjustments to the Iray rendering output.


✱  Note: you may want to consider disabling tone mapping when exporting a render with high dynamic range.


• Exposure:
  • Exposure Value: controls the overall exposure of your scene. Increasing the value reduces the exposure, darkening the image. Conversely, decreasing the value increases the exposure, brightening the image. Positive values tend to underexpose; negative values tend to overexpose.
• Highlights/Shadows/Color:
  • Highlight Recovery: controls the compression of highlights in the image, to enable recovery of overexposed highlight detail by compressing the upper end of the brightness range. The higher the value, the more the highlights will be compressed. Setting a value of 0.0 means no compression.
  • Shadows: controls the strength of shadows. The higher the value, the darker the shadows. Setting a value of 0.0 will leave the shadows unaltered.
  • Saturation: controls the strength of color. A higher value will result in more intense colors; a lower value will result in paler colors.
• White Balance:
  • Predominant Lighting: adjusts the color of the scene based on the type of lighting used. Select the color temperature from a dropdown list of preset lighting types, each with the corresponding Kelvin value:
    • D50 Horizon light (5003k)
    • D55 Mid-morning/afternoon daylight (5503k)
    • D65 Noon daylight (6504k)
    • D75 North sky daylight (7504k)
    • F1 Daylight Fluorescent (6430k)
    • F2 Cool White Fluorescent (4230k)
    • F3 White Fluorescent (3450k)
    • F4 Warm White Fluorescent) (2940k)
    • F5 Daylight Fluorescent (6350k)
    • F6 Light White Fluorescent (4150k)
    • A Incandescent/Tungsten (2856k)
    • Phosphor Mercury (6800k)
    • Xenon (6400k
    • Mercury (4000k
    • Quartz (3350k)
    • Halogen (3000k)
    • High Pressure Sodium (2200k)
    • Neutral
  • Custom (Kelvin): specify the color temperature directly via the Kelvin value of the light.
