cheers Gary
if you did youre processing in the jpg format you might get this, check the histogram of the finished image , does it have gaps or is it smooth?
i proccess in 16 bit TIFF ..... thats the first thing that comes to mind, as it suggests missing tonal range providing a discreet "step"

i cant see why 400 would be different providing you have got solid data to start with.
