Hi Guys,
Well who would have thought after all this time struggling with flats, processing etc, that I, yes me was the one causing all the problems.
I would always convert my Raws to Tiff's in another program, and then bring then across to Image Plus, where I would process then, and end up with the results that have been bugging me for ages.
I have just realised ( with help from some of you good people) that I can convert my Raws to Tiff's in Image Plus,
and boy has that made a difference, the problem is solved, and the vignetting is gone.
So that crappy short exposure I did, with the Modded 5D for a test run has come out reasonably well, it has been stretched plenty, and played around with so it probably isn't of the highest quality, but the future looks promising.
Thank you so much for all your help.
Leon
