Adjust the minimum, maximum and in-between intensity of the red, green and blue channels according to individual threshold parameters.

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.

Threshold: Red / Green / Blue
Use these parameters to control the threshold value which defines the split between the "pass" and "fail" intensities. A value of 0.5 means that the channel is split at its mid-intensity level.

Pass: Red / Green / Blue
Use these parameters to define the maximum intensity that the portions of your image above the threshold should be assigned. This value is assigned more or less uniformly depending on the Sharpness parameter. No pixel in your output image will have an intensity value for the channel above this value.

Fail: Red / Green / Blue
Use these parameters to define the maximum intensity that the portions of your image below the threshold should be assigned. This value is assigned more or less uniformly depending on the Sharpness parameter. No pixel in your output image will have an intensity value for the channel below this value.

Sharpness: Red / Green / Blue
Use these parameters to control how the "pass" and "fail" intensities should be applied to your image. A Sharpness value of 1.0 means that the image will be clearly split in two discrete areas, each one filled with one of the assigned intensities. Lower sharpness values introduce a linear interpolation of the pass and fail intensities.

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.
