ToneMap
Tone-mapping takes an HDR buffer as input, and remaps its color to a [0, 255] range so we can display it on a screen.
There are many ways to remap colors from an HDR space to an LDR, depending on the formula you choose.
Stride supports several tone-mapping operators out of the box:
- Reinhard (the classic operator)
- Exponential
- Logarithmic
- Drago
- Hejl-Dawson
- Mike-Day
- U2-Filmic
