Sorry to hear of your ruined film, Peter. 🙁 You know, I think destruction of negs is harder to take from a lab, because it's largely out of one's own control... frustrating and helpless. If you were processing the film yourself, and screwed up badly, ruining a roll or two, it would be infuriating but you can stand kicking yourself only so much! The comforting part there is that YOU can control the improved procedure next time to prevent a repeated disaster. And you can process your own XP2 at home! 🙂
