Thanks Patrick. I know thats part of the problem. But is thier a Rule to apply?

In that C image set up I started  again with a re-entry of Howies original clouds/lights. and placed it in the background with out any reduction in size.. I note that all the light in my original save had set themselves back to 100 and 400".

Ok. I reset the lights to Howies settings.But the render of this has nothing resembling Howies original.  Beatsme.
