In this overview you will see how each parameter in a map effect the output, it is represented in a Photoshop styled curve.
I take no responsibility if you get dizzy and puke.
This is how the overview is organized.
- Map
- Parameter
- Two animated curves moving in 10 or 0.1 increments, depending on the parameter.
The first curve is minus and the second curve is plus.
I will add more in the future, feel free to request.
ColorCorrection
Standard - Brightness


Standard - Contrast


Advanced - Gain


Advanced - Gamma/Contrast


Advanced - Pivot (This parameter will move the gamma endpoint)


Advanced - Lift/Offset


Output
Output Amount
This parameter behaves weird on the curve, Lord Ondra has the answer:
Ondra: Output Amount differs from RGB level in that the first one will also influence gamma.
RGB Offset


RGB Level


RGB Multiply
Output Amount (White to Black)

VRayHDRI
Overall Mult


Inverse Gamma (This is the same as “Advanced - Gamma/Contrast” in the “ColorCorrection” Map
