Equalize
Remaps the black and white points in an image, resulting in individual adjustments to
the contrast in the dark and light parts of an image. The Equalize filter can be used to
adjust the overall contrast range of an image, crushing the whites and blacks, or it can
be used to create selective washed out or darkened effects.
Parameters in the Inspector
Input Black: Sets the relative color value used for black. Values range from 0 to 1.0.
Input White: Sets the relative color value used for white. Values range from 0 to 1.0.
Dashboard controls
The Dashboard contains the same controls as the Inspector.
Gamma
The Gamma filter adjusts the relative distribution of brightness within the midtones of
an image, while leaving the white and black points alone. The perceived result is to
brighten and darken the areas of medium brightness within an image, while leaving
the highlights and shadows alone. This avoids a washed-out result.
This is one the most useful filters for correcting poor exposure in images, and should
almost always be used first before trying the Brightness filter.
Parameters in the Inspector
Gamma: Sets the gamma correction. Values range from 0 to 5.
Dashboard controls
The Dashboard contains the same control as the Inspector.
