Logarithmic_Exposure_Control - superclass: ToneOperator; super-superclass:MAXWrapper - classID: #(1488218187, 1350530793)
Logarithmic Exposure Control uses brightness, contrast, and whether the scene is outdoors in daylight to map physical values to RGB values. Logarithmic Exposure Control is better for scenes with a very high dynamic range.
Logarithmic Exposure Control is the best type of exposure control for animations, since it doesn't use histograms.
Enable/Disable the Tone Operator. Changes the state of the Active checkbox in the Environment/Exposure Control rollout
Get/Set the Brightness value of the Tone Operator.
Get/Set the Chromatic Adaptation value of the Tone Operator. Corresponds to the Color Correction checkbox in the Tone Operator’s rollout.
Get/Set the Color Differentiation value of the Tone Operator. Corresponds to the Desaturate Low Levels checkbox in the Tone Operator’s rollout.
Get/Set the Contrast value of the Tone Operator.
Get/Set the Daylight switch of the Tone Operator.
Get/Set the Exterior switch of the Tone Operator.
Get/Set the IndirectOnly switch of the Tone Operator. Corresponds to the "Affect Indirect Only" checkbox in the UI.
Get/Set the Exterior value of the Tone Operator.
Get/Set the physicalScale value of the Tone Operator.
Get/Set the state of the processBG value corresponding to the "Process Background and Environment Maps" checkbox in the Tone Operator’s rollout. When set to true, the Tone Operator will affect the background.
Get/Set the whiteColor value of the Tone Operator. When the chromaticAdaptation is set to true, the Tone Operator will shift all colors so that the color set in whiteColor appears as white.
Set this property to true when working with exterior Daylight scenes.
NEW in 3ds Max 9: When set to true, the exposure control will use the old algorithm (pre-3ds Max 9). When set to false (default), the new algorithm will be used.
The tone mapping algorithm used in the logaricthimic exposure control has been changed in 3ds Max 9.
The old algorithm would scale all three color components (R, G, B) in an identical manner, based on the perceptible luminance of the color. The algorithm produces results which were usually over-saturated, and yellowish.
The new algorithm maps the three color components independently, and the perceptible luminance is not taken into account. This results in images which are much less saturated (more grey) and much more realistic.
