Thank you for joining Lightpainters United but in my opinion to be considered light painting there needs to be painting: active endeavours to control how and when lights are captured and not merely a capture of what is there with your only input being the settings of the camera and the composition before you hit the shutter. Long exposures are not by defenition light paintings. Light painting can be done with available light and doesn't have to happen in front of the lens: camera movements, focus, zoom, filters etc are all considered light painting if changed during the exposure.
Nice traffic trails though.
