| sRGB | srgb | Standard RGB transfer curve |
| Linear | linear | Linear light transfer (no gamma) |
| Gamma 1.8 | gamma18 | 1.8 gamma (classic Mac) |
| Gamma 2.0 | gamma20 | 2.0 gamma |
| Gamma 2.2 | gamma22 | 2.2 gamma (PC standard) |
| Gamma 2.4 | gamma24 | 2.4 gamma (cinema) |
| Gamma 2.6 | gamma26 | 2.6 gamma |
| Gamma 2.8 | gamma28 | 2.8 gamma |

| HLG | hlg | Hybrid Log Gamma (BBC/NHK HDR) |
Default: BT.1886
Recommended Settings
Use BT.1886 for most SDR displays -- it is the broadcast standard and provides accurate shadow rendering. Use sRGB if your workflow is computer/web oriented. The pure gamma options (1.8 through 2.8) are useful for matching specific display calibration targets. PQ and HLG are HDR transfer functions and should only be selected when outputting to an HDR-capable display in SDR menu context.
