Tone Mapping
The tone mapper allows various controls over the look of your scene. These can be used during rendering without interrupting progress. These can be found in Render Setup > Settings tab, under the Tone Mapper rollout:
- Enable Tone Mapping: make interactive visual adjustments to the Iray rendering output. You may want to disable tone mapping if you are exporting a scene with high dynamic range.
- Exposure Value: control the overall exposure of your scene. Increasing the Exposure Value reduces the exposure, darkening the image. Decreasing the Exposure Value increases the exposure, brightening the image.
- Highlight Recovery: recover overexposed highlight detail by compressing the upper end of the brightness range. Setting a value of 0.0 disables the effect.
- Shadow: control the strength of shadows. The higher the value, the darker the shadows. Setting a value of 0.0 leave the shadows unaltered.
- Saturation: control the strength of color. A higher value gives more intense colors, a lower value gives paler colors.
- White Balance:
- Predominant Lighting: adjust the color of the scene based on the type of lighting used. The dropdown menu lists several options, each with the corresponding Kelvin value:
- Full Spectrum
- 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
- Custom (Kelvin): specify the color temperature directly via the Kelvin value of the light.
