Tone mapping method This field shows or sets the tone mapping algorithm to use for HDR10 to SDR dynamic range conversion. reinhard: preserve overall image brightness with a simple curve, using nonlinear contrast, which results in flattening details and degrading color accuracy. hable: preserve both dark and bright details better than reinhard, at the cost of slightly darkening everything. Use it when detail preservation is more important than color and brightness accuracy. mobius: smoothly map out-of-range values, while retaining contrast and colors for in-range material as much as possible. Use it when color accuracy is more important than detail preservation.
