Falling is a single, in-camera multiple exposure using the Zeiss Otus 55mm f/1.4 and a Nikon D800 on a tripod. There was a black backdrop, and I used a studio strobe on either side, facing the model who was posing on a suspended hoop. The mechanics of in-camera multiple-exposure photography aren’t too tough to master provided auto-gain is enabled. But creating these images does require precision choreography and communication with the model to get the posing positions right, otherwise the composition doesn’t come together.
You can see some of the other images I’ve made using this technique in these stories: Wheel of Life; Dance in the Rings; A Rorschach for MFAs and Multiple Exposures. Also check out the Multiple Exposures portfolio page of these images!
