Class AutoExposureSettings

Determines how quickly does the eye adaptation adjust to smaller values. This affects how quickly does the automatic exposure changes when the scene brightness decreases. In range [0.01f, 50.0f].

Determines how quickly does the eye adaptation adjust to larger values. This affects how quickly does the automatic exposure changes when the scene brightness increases. In range [0.01f, 20.0f].

Percentage above which to ignore values in the eye adaptation histogram. The histogram is used for calculating the average brightness of the scene. Total luminance in the histogram will be summed up and multiplied by this value to calculate maximum luminance. Luminance values above the maximum luminance will be ignored and not used in scene brightness calculations. This allows you to remove outliers on the high end of the histogram (for example a few very bright pixels). In range [0.0f, 1.0f].

Percentage below which to ignore values in the eye adaptation histogram. The histogram is used for calculating the average brightness of the scene. Total luminance in the histogram will be summed up and multiplied by this value to calculate minimal luminance. Luminance values below the minimal luminance will be ignored and not used in scene brightness calculations. This allows you to remove outliers on the lower end of the histogram (for example a few very dark pixels in an otherwise bright image). In range [0.0f, 1.0f].

Determines should automatic exposure be applied to the HDR image. When turned on the average scene brightness will be calculated and used to automatically expose the image to the optimal range. Use the parameters provided by autoExposure to customize the automatic exposure effect. You may also use exposureScale to manually adjust the automatic exposure.

When automatic exposure is turned off the camera's f-stop, shutter speed and ISO speed are used for determining the exposure. In that case you can also use exposureScale to further tweak the exposure.

Clamps the maximum eye adaptation range to this value. This allows you to limit eye adaptation so that exposure is never too low (for example when looking at a very bright light source you probably don't want the exposure to be so low that the rest of the scene is all white (overexposed). Represented in EV100 units. In range [-10.0f, 20.0f].

Clamps the minimum eye adaptation range to this value. This allows you to limit eye adaptation so that exposure is never too high (for example when in a very dark room you probably do not want the exposure to be so high that everything is still visible). Represented in EV100 units. in range [-10.0f, 20.0f].

Marks the object as dirty.

Allows modifying this object multiple times in a row in a scope, without marking the object dirty immediately. Dirty flags are accumulated and the object is marked dirty at the end.
