Catherine -

Assuming that the lab made the print on black and white paper, you can very
carefully bleach the portions you want to lighten.

Water (125 deg F or 52 deg C) - 750.0 ml
Potassium Ferricyanide - 50.0 grams
Potassium Bromide - 10.0 grams
Sodium Carbonate, monohydrated - 20.0 grams
Add cold water to make - 1.0 liter

I believe that you will need to refix the print following the bleach (and
perhaps Spottone any areas that were bleached too far). This is not an easy
thing to do.

Another thing would be to use Spottone to touch up the negative, though that is
much easier than it sounds.
