The effect I see isn't any sort of reflected or ghost image, more a 
light fogginess bleeding from the light area into the dark. The 
transparency that shows it best is a black trouser leg against a 
white car. There are no really bright small areas - the LS2000 
handles these fairly well. Like with cameras, the worst effect is 
from large bright areas not small very bright ones.
