Ah. Thanks Ravynsworld for the explanation of the clouds version. That will come in very handy for slightly grubby metal - that is IF the clouds thing will also work on the plain brushed metal at the top of this thread... At present though I'm trying to get a clean new metal effect. and not getting very far... When I boost the brightness & contrast on it I get this banding (see pic) even on the highest radial blur - I don't want that. I'm trying for something more like Lunqvist's version in message 2 above - but without the light and dark zones - I need it to be uniform. Is this possible?
