A couple of years back, when I was a not-so-young scrub at Time, I had the opportunity to work on an article about skatepark design with Richard Lacayo. In reporting the story, the designers we spoke with talked a lot about “lines.” Not just the lines of their designs, but the lines that skaters take as they carve their way through a half pipe or bowl. Being a non-skater, I was left to imagine these possible trajectories. Not anymore.

Last week, I stumbled into the photographs of Lia Halloran at Mark Moore in Santa Monica. Halloran takes long exposure pictures of herself working her way through a variety of parks at night, with a flashlight or some other light source strapped on. No need to imagine lines here. They’re etched in light, right into the photo. It was an incredible way to see these concrete monuments come to life. Above is a shot from the skater-built park under the 110 Freeway in San Pedro, south of L.A.

The photos at Mark Moore are on display as part of the group show Ultrasonic International, through October 25th. If you’re in Miami, some of her photos just went on display at Fredric Snitzer, and they’ll be up through November 10th. You can see many more pix on her website, here. (Though it’s no replacement for seeing them live.)
