Inputs

Method
EAutoExposureMethod Enum

Luminance computation method

Low Percent
Float

The eye adaptation will adapt to a value extracted from the luminance histogram of the scene color. The value is defined as having x percent below this brightness. Higher values give bright spots on the screen more priority but can lead to less stable results. Lower values give the medium and darker values more priority but might cause burn out of bright spots. >0, <100, good values are in the range 70 .. 80

High Percent
Float

The eye adaptation will adapt to a value extracted from the luminance histogram of the scene color. The value is defined as having x percent below this brightness. Higher values give bright spots on the screen more priority but can lead to less stable results. Lower values give the medium and darker values more priority but might cause burn out of bright spots. >0, <100, good values are in the range 80 .. 95

Min Brightness
Float

A good value should be positive near 0. This is the minimum brightness the auto exposure can adapt to. It should be tweaked in a dark lighting situation (too small: image appears too bright, too large: image appears too dark). Note: Tweaking emissive materials and lights or tweaking auto exposure can look the same. Tweaking auto exposure has global effect and defined the HDR range - you don't want to change that late in the project development. Eye Adaptation is disabled if MinBrightness = MaxBrightness

Max Brightness
Float

A good value should be positive (2 is a good value). This is the maximum brightness the auto exposure can adapt to. It should be tweaked in a bright lighting situation (too small: image appears too bright, too large: image appears too dark). Note: Tweaking emissive materials and lights or tweaking auto exposure can look the same. Tweaking auto exposure has global effect and defined the HDR range - you don't want to change that late in the project development. Eye Adaptation is disabled if MinBrightness = MaxBrightness

Speed Up
Float

>0

Speed Down
Float

>0

Exposure Bias
Float

Logarithmic adjustment for the exposure. Only used if a tonemapper is specified. 0: no adjustment, -1:2x darker, -2:4x darker, 1:2x brighter, 2:4x brighter, ...

Exposure Bias Curve
Curve Float Object Reference

Exposure compensation based on the scene EV100. Used to calibrate the final exposure differently depending on the average scene luminance. 0: no adjustment, -1:2x darker, -2:4x darker, 1:2x brighter, 2:4x brighter, ...

Histogram Log Min
Float

temporary exposed until we found good values, -8: 1/256, -10: 1/1024

Histogram Log Max
Float

temporary exposed until we found good values 4: 16, 8: 256

Calibration Constant
Float

Calibration constant for 18% albedo.
