This color adjustment lets you define a new output range for the pixel values of your input media. This effect can be used to decrease contrast, lighten shadows, darken highlights, etc.

This effect was designed to give you similar functionality to what is available in image retouching programs such as Adobe® Photoshop®. A related effect is the Crush Color plug-in, also part of FxFactory Pro.

Effect Parameters

Presets
Presets contain a snapshot of the plug-in parameters. The Presets control lets you choose among one of the presets built into the plug-in, save current parameter values to a preset file, or load an existing preset file from disk.
A preset file saved to disk via the "Save As" button can be loaded from another instance of the same plug-in by clicking the "Open" button. Presets generated in one host can also be loaded from the same plug-in when used in a different host.

Adjust Channels
This parameter lets you control whether the Low, Mid and High levels are adjusted as a whole, or separtely, for all channels in the source image. The available options are
  • Together: three sliders are available for adjusting the effect.
  • Separately: twelve sliders are available for adjusting the effect.

Low / Mid / High
These sliders control the new output range that any given pixel value will have in the output. To produce an output image that is identical to the input, leave the “Low” value to 0, the “Mid” value to 0.5 and the “High” value to 1.
Raising the “Low” value has the effect of making shadows in the image appear lighter. Similarly, lowering the “High” value will cause highlighs to appear dimmer. As the output range becomes smaller than the input range, this effect allows you to reduce contrast.

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.
