camera_auto_exposure
Auto exposes the main camera.
Currently supports the 'mia_exposure_photographic' and 'falsecolor_tonemapper' tonemappers.
Note that for the 'falsecolor_tonemapper' to make use of the returned min and max luminance values, the iray_firefly_filter needs to be turned off.
arguments
- "center_weight" : Float32 (default: 0.7)
When doing weighted metering, this defines the ratio (value between 0.0 and 1.0) between how much the center and the offcenter areas affect the calculations. Does not apply in full screen metering.
- "exposure_compensation" : Float32 (default: 0)
The fStop offset to apply to the calculated fStop, this may affect the camera shutter speed in order to compensate.
- "f_stop_maximum" : Float32 (default: 32)
The maximum that the calculated f stop can be.
- "f_stop_minimum" : Float32 (default: 0)
The minimum that the calculated f stop can be.
- "metering_mode" : String (default: "full_image")
The metering mode to use.
Possible Values:
- full_image
- spot
- center_weighted
- "metering_radius" : Float32 (default: 0)
The percentage (between 0.0 and 1.0), of the minimum resolution dimension to use as the metering radius.
- "original_camera_shutter" : Float32 (default: false)
The original camera shutter value to use to calculate the f number. By default the camera shutter value on the camera is used.
- "render_samples" : Sint32 (default: 15)
The number of render samples to do for the exposure test.
- "renderer" : String (default: "default")
The renderer to use.
Possible Values:
- default
- iray
- hybrid
- preview
- rt_bsp
- gpu
- sketch
- "resolution_x" : Sint32 (default: 160)
Resolution of the render to do the exposure testing on.
- "resolution_y" : Sint32 (default: 120)
Resolution of the render to do the exposure testing on.
- "scene_name" : String
The name of the scene.
- "set_onto_camera" : Boolean (default: true)
When true, the result is set directly onto the scene camera.
- "use_standard_deviation" : Boolean (default: false)
When true, a standard deviation is calculated for the luminance.
