highlightCompensation enabled When enabled, Katana adaptively compresses pixel values

prior to transform filtering and re-expands them afterwards.

This helps to reduce the ringing in high-contrast areas that can

be a problem in linear floating point images.

clampOutput enabled Filtering can introduce negative values and send values above

1.0.

When clampOutput is enabled, Katana clamps the RGB

channels low at 0 and the alpha channel between 1 and 0 after

the image is filtered. This is recommended for transforms on

color/alpha images.

When clampOutput is disabled, no clamping is done and

values below 0 and above 1 are allowed. This is recommended

for transforms applied to images that contain data which may

(correctly) range more widely.

ImageSaturation

This node is used to correct the input image's saturation (color intensity).
