Leveller 2.5 alpha now at build 912. Radial blur improved, Zoom blur implemented. They can be a little slow (e.g., 512 x 512 document at 1.6 Ghz takes 20-40 seconds for modest blur distances). Zoom blur uses lower/upper scaling percentages instead of a single strength parameter (but it's easier to tell what will happen). http://www.daylongraphics.com/products/leveller/download/lev25a.zip Ray
