Set Exposure
Set auto exposure on a volume, override bits included. Refuses a min/max pair that would stop eye adaptation unless you say you mean it, and refuses values outside the engine's own declared clamp range, which a reflection write would otherwise store silently. For the histogram-only settings use hf_set_post_process_setting.
hf_set_exposureWriteArguments
| Name | Type | Description |
|---|---|---|
volumereq | string | |
bias | number | Exposure compensation, in stops. Read by every method. |
force | boolean = false | Edit even when the asset cannot currently be saved - for example when revision control is configured but disconnected. The change will be made in memory and WILL BE LOST unless the underlying problem is fixed before saving. Only pass this if you intend to discard the work or fix the connection first. |
lock_exposure | boolean | Required to set min equal to max, which turns eye adaptation OFF. Without it that pair is refused. |
max_brightness | number | The same unit as min_brightness. |
method | string | Histogram, Basic or Manual. Manual IGNORES min, max and both speeds. |
min_brightness | number | In EV100 or cd/m2 depending on the project's ExtendDefaultLuminanceRange setting, which the result names. Equal to or above max stops eye adaptation. |
speed_down | number | F-stops per second adapting to a darker one. |
speed_up | number | F-stops per second adapting to a brighter scene. |
