Motion: Levels

Levels

Provides controls to remap the white and black points of an image, with a gamma control to adjust midtones, all at once. A histogram provides an analysis of the image to help you judge the adjustments to make.

A powerful option in this filter is the ability to make independent adjustments to the red, green, blue, and alpha channels of a layer.

Adjust this filter using the parameter controls in the Filters Inspector:

  • Histogram: Displays an analysis of the layer. By default, the RGB channels are selected. A pop-up menu can be used to select Red, Green, Blue, or Alpha channels for viewing.

    Click the disclosure triangles to expose the RGB, Red, Green, Blue, and Opacity parameter groups. Click the group parameter disclosure triangles to display sliders:

    • Black In: Sets the In point for black, below which values are considered black.

    • Black Out: Sets the minimum brightness value that appears in the output. Other values are scaled between Black Out and White Out values.

    • White In: Sets the In point for white, above which values are not output.

    • White Out: Sets the maximum brightness value that appears in the output. Other values are scaled between Black Out and White Out values.

    • Gamma: Sets the amount of gamma correction.

  • Mix: Sets the percentage of the original image that’s blended with the color-corrected image.
