"It just blew my mind because it was so surreal and seemed almost manipulated. It got stuck in my head and I knew I had to shoot something there."
It was a tricky shoot to organise. For starters, Lorenz didn't know whether the arches were actually rideable. He also needed to keep the structure in focus, while capturing the action, so he had to use a small aperture (large f-stop) and a fast shutter speed – which meant he had to push up the ISO. "It was a thin line between grain, depth of field and shutter speed," he explains.
After two days of getting to grips with the unusual skating surface and experimenting with the light and the positioning, his hard work paid off and Lorenz got his shot. "When I saw the light in that tunnel, with tiny shadows on each arch, and then the skateboarder doing his trick, it was an amazing feeling," says Lorenz. "I knew this was the shot because the trick was so on point and the light was perfect, with slight beams coming from the sides. I thought about whether we could do anything better – any other position, any other light – but I saw the picture and knew that was it.
"It's tempting to shoot the picture in a different way, to get it done sooner – but I don't want to look at an image and think 'Oh, it's nice, but it could have been better.' Being patient is tough, but I have to force myself to wait."
