Well, to be honest, she was not actually in Switzerland. This is another of my on-going film swap project. I shot Rae in my studio in Toronto then mailed the film to Martin Klöckner in Zurich. He then spent a bit of time by a local lake taking the second exposures.
Both Martin and I were using Hasselblad 503 cameras so the frame registration was not too far off. The film was Ilford's HP5. I don't know how he developed nor scanned it.
