- <description>
- PsdExposureEffect adjusts the exposure of an image. The function is made
- up of three properties (exposure, offset and gamma). These properties
- are applied to all three RGB color channels. Alpha is not affected.
-
- Additionally, there is a property that informs the effect of the nature
- of the color data of the image, that is, the relationship between the pixel
- values and a linear-energy domain. This property is called ImageGamma,
- and should be used to define the type of pixel data, and should not be used
- as an adjustment parameter. Typically, the ImageGamma value is obtained from
- the RGB working space associated with the image. Common values are 1.0, 1.8 or 2.2.
