Retouch 47 photos per specification removing dirt and, on the black girl, skin blemishes. On the older woman leave wrinkles and age spots. Whiten teeth up a bit. Correct color and contrast to normal on the older woman's pics. Match black girl's pics against yellow wall to 1st in series. Fix exposure on white fence series. Consider perspective and whether it can be feasibly corrected on those to a more pleasing one -- and if not we'll live with it.
This is not open to all. If you weren't invited withdraw your bid.
