Thanks Dave , Mark I suddenly thought this could be the case in onne of those just falling asleep moments of clarity, I will have to check it, I was using 1/250th at the time. Also thanks Tim , "that an exposure made to give a density of, say RGB 180ish will have a variation of about 10 points RGB between one spot and another. I can't see it in any image with a subject, just when testing. I have used different cameras, and they are each different." I also do not see it in any image that has real "subjects" in it just appears on white backdrop shots across the bottom of the frame (Landscape).
