This pic has been shot by Stuart Pitcher at Capital FX in London in 1993. They have been asked to replace the head of Princess Diana with a shot of Actress Kristin Scott Thomas for the final shot in the film. The face replacement was achieved in photoshop and then printed onto high quality photographic paper to be filmed under a Rostrum Camera. This was the best way to get the image onto 35mm film as it was still the early days of digital fx.
Only one print has been ever made, this one.
