Local contrast enhancement increases the appearance of light-dark transitions in your source media.
This effect was designed to give you similar functionality to what is available in image retouching programs such as Adobe® Photoshop®.
Effect Parameters
Radius
The radius parameter controls the size of the area around each pixel that is examined during the color adjustment process.
Contrast
This parameter controls the intensity of the effect.
Color Space
This parameter allows you to choose a working color space for the effect. When the “Linear” option is selected, the plug-in will convert all color values to a non-gamma-corrected format. When the “Uncorrected” option is selected, the color values supplied by the host will be used directly, without conversion. It may help to choose “Uncorrected” when dealing with smooth gradients or vector-art backgrounds, or if you have already applied gamma correction to your source media in a previous step of your workflow.
High-precision Output
This parameter, available only inside Final Cut Pro, controls the color range of the final output. Although you will see no difference in the Canvas window (due to the fact that Final Cut Pro always previews in 8 bit color) high-precision clamping ensures that your output falls within a predictable range. This feature will often save you an extra post-processing step and come in handy when the only previewing device available is the built-in display.
