CV HDR Tonemap
Compresses a float radiance map (from 'HDR Merge to Radiance') into a displayable 0..1 image. 'linear' only gamma-corrects; Drago/Reinhard/Mantiuk are tone-mapping operators that keep detail in both shadows and highlights. The method-specific knobs are advanced inputs - each is used only by its own method.

Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| radiance | NPARRAY | HxWx3 float32 radiance map from 'HDR Merge to Radiance'. | |
| method | COMBO | Reinhard | Tonemapping operator. linear = plain gamma; Reinhard is a safe default; Drago suits very bright scenes; Mantiuk is contrast-domain. |
| gamma | FLOAT | 2.20.1–5 | Gamma applied by every operator. 1.0 = linear; 2.2 matches a typical display; higher brightens midtones. |
| saturationopt | FLOAT | 1.000–3 | Drago/Mantiuk only: color saturation of the result. |
| biasopt | FLOAT | 0.850–1 | Drago only: bias of the tone curve (0.7-0.9 typical). |
| intensityopt | FLOAT | 0.0-8–8 | Reinhard only: overall brightness (- darker, + brighter). |
| light_adaptopt | FLOAT | 1.000–1 | Reinhard only: 1 = fully local adaptation, 0 = global. |
| color_adaptopt | FLOAT | 0.000–1 | Reinhard only: 1 = per-channel (auto white-balance) adaptation, 0 = shared across channels. |
| scaleopt | FLOAT | 0.700–2 | Mantiuk only: contrast scale factor (0.6-0.9 typical). |
