Chromatic_adaptation_GL

Chromatic_adaptation_GL

This shader performs a chromatic adaptation. It also takes care of any necessary color space conversions.

INPUT(S)

• Source : Connect the image you want to apply the effect onto. (RGB)

HOW TO USE IT

Input

• Input Colour Space : Input colour space. Note that the input must be linear in all cases.
  • ACEScg
  • ACES2065-1
  • Rec. 709
  • Rec. 2020
  • P3D65
  • XYZ
• Input White Type : Input white point type.
  • Native
  • Illuminant
  • Colour Temperature
  • XY Coordinates
  • from Colour
• Input Illuminant : Input white point illuminant.
  • ACES
  • HD D65
  • DCI
  • Equal Energy

---

• Input Temp : Correlated colour temperature of the input white point (per Illuminant series D).

• Input Tint : Correlated colour tint of the input white point.

• Input Temp Shift : Applies a scaling of the colour temperature by a factor of 1.4388/1.438 to mimic the CIE D-series behavior instead of maintaining the physical exact correlated colour temperature.

• Input Coordinates : CIE 1931 xy coordinates of the input white point.

• Input Colour : Colour representation of the input white point.

• Input Surround : Viewing conditions.

  • Average
  • Dim
  • Dark

• Input Field Luminance : Input field luminance.

• Input Relative BG : Relative input background brightness compared to the scene white.
