Light Graffiti Tutorial

Using an exposure of about ten-to-thirty seconds and a tripod for best results, Light Graffiti artists start at the first click. Glowsticks, flashlights, reflectors, and even torches have been used as mediums to create all sorts of designs and tags, as the artist becomes a ghost of a blur, if visible at all.
