I usually find the GradFilter very useful but there are times when I wish to darken a sky but the are foreground objects in the sky area too.
Does anyone know if there is a way to make the Grad operate on only the brighter parts of the image in a similar way to the Metagrad PhotoShop plugin from Xero Graphics?
