Hurricane Sower.
I had this idea for a long time. I built the ladder, bought the nightgown, and waited almost a year for a hurricane to came in. Finally when hurricane Irene arrived, we went to location just hours before the hurricane hitted land. Wind and rain were hard so we just had about 10 minutes to do the shot: Pre-focusing, then cleaning water hiiting the lens and shooting fast... It's one shot, in camera, no composite.
Fun fact... The model's name was Irene as well.
