Oliver: Thanks for your feedback. 1) The corrected image includes some
toning, so I would expect that, I guess. 2) How is the uncorrected photo
displayed on your monitor? Does it have a slight brownish tint? 3) Even at
daylight (no artificial lighting) I notice a slight warm/brownish tint when
I look at the printed photos. Perhaps, however, it's a question of taste.
Regards, Francisco
