Some photos taken at the Superhero Street Fair (Islais Creek Promenade, San Francisco).­

Photos of performers spinning LED-light or laser hula hoops and staffs.­

I general I used a combination of long-exposure and flash, to capture the beautiful light trails while the performer is frozen by the flash, so it does not appear blurred.­ It is not an easy technique but the results are amazing.­
