Thanks Mike. I'm using flat lights, flat darks and darks. For whatever reason I have to over stretch the image to get any detail out of it, that in turn is killing the background. That's when I process in DSS anyway.
I did the same set of data in Iris and have improved the result, especially the background. I think the difference all happens during the asinh stretch command in Iris, I don't understand what that command does, but when you play with the values (alpha & intensity) of that stretch it makes all the difference. I have yet to find something in DSS to have the same effect.
Thanks again
George
