Control (UI) Default Value Function
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 (as we
have in Katana).
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.
ImageDivide
This node layers images together using the Divide compositing algorithm: B/F. It divides the background values by
the foreground values.
You can also specify a different compositing algorithm using the operation control.
Control (UI) Default Value Function
R enabled When enabled, affect the red channel of the image.
G enabled When enabled, affect the green channel of the image.
B enabled When enabled, affect the blue channel of the image.
