[Leica] Film exposure error - how to correct it

[mark at rabinergroup.com (Mark Rabiner)]

You need a two-stop push. Lots of custom labs can do that. You?ll still have 
very thin shadows if they?re there at all but at least your film will not be 
under developed and can be printed with normal grades of paper.
You may get a few viable images off the roll.

    My advice would be to talk to the lb guy at Ilford, I feel sure he will 
give it the best treatment.
