The amount of blurring achieved by a gaussian blur is specified by the standard deviation of the blurring kernel not the size of the blurring kernel. This probably means that GIMP and Photoshop use different ways of computing the standard deviation used from the user specified radius. Using the size of the kernel (which probably is ~2.5x the standard deviation) might be leading to behavior similar to what GIMP is doing. /Øyvind K. -- «The future is already here.
