Tone Mapping

SettingDescription
Tone Mapping Operator Select Tone Mapping Method. All operators except Clamp apply the exposure adjustment based on the parameters below or the results of the auto-exposure feature.
  1. Clamp: leaves the radiance values unchanged, skipping any exposure adjustment
  2. Linear: applies the exposure adjustment but leaves the color values otherwise unchanged
  3. Reinhard: operator based on Erik Reinhard's tone mapping work
  4. Reinhard (modified): variation of the operator based on Erik Reinhard's tone mapping work
  5. HejiHableAlu: John Hable's ALU approximation of Jim Heji's operator
  6. HableUC2: John Hable's Uncharted 2 filmic tone map
  7. ACES: operator based on the Academy Color Encoding System
  8. Iray: Reinhard-based operator that matches the operator used by NVIDIA Iray by default
cm^2 Factor Use this factor to adjust for scene units being different from centimeters
White Point A color that will be mapped to white on the output
Film ISO Simulates the effect on exposure of a camera's ISO setting
Camera Shutter Simulates the effect on exposure of a camera's shutter open time
f-Number / f-Stop Simulates the effect on exposure of a camera's f-Stop or f-Number aperture
