No, I don't use the dials, I use the editing tools, - "scale", "twist", "rotate". It makes it easy to position or move the circles that represent the fall-off-zones. But it isn't a very accurate way. I don't seem to find where the exact figures for them are. I've done a search in the cr2 files for zones... when I search for "zone" it finds "smoothZones". I suspect they are not the same as the fall-off-zones, - are they?? Britt
