This was taken using the Olympus E-M10 ii, and the Lumix 20 mm prime lens. This is the tail light of a stationary car, only lit by an overhead street light at night. The white light is the reflection of street light on the car paint. This is an ICM + doble exposure, more or less straight out of camera. The stars aligned when I took these, I haven't been able to capture something equally good after this (yet).
1 sec exposure, f/5.6, ISO 200.
