This is a creative photo technique that produces light trails in your night photos.- Position your camera on a tripod and compose. It's best to have a bit of moon light or city building lights in the shot, as well as a road of some sort. (maybe, a high traffic area)
- Set aperture/shutter speed according to the guide. Your shutter will have to stay open for extended amount of time (the photo above had an exposure of around 30 seconds), allowing the light from the cars' headlights (and taillighs) to register on film by leaving a trail of light. Braketing will ensure usable results (30, 45, 60 seconds).
- Touch up in Photoshop or other photo-editing program to achieve some creative and unique results (i.e. experiment with levels, filters, color balance, etc...)
- Submit your photos to Sergykal Studios Critique Program to get some feedback.
