Transcription: Shutter took the most preparation of all the workshops and was the last workshop shot. Extensive testing showed that timing the shots by hand and eye was not accurate enough, and we had to develop a sophisticated timing system to automatically trigger the camera. Our first attempt to shoot Shutter turned out to be the beginning of a record-setting rainstorm. When we finally got back together, everything worked great, and the experience of the girls of the Iguala racing team really helped in the cycling sequence.
