One of my favorite subjects to photograph are light trails. This night my wife and I were returning from a function and she was driving her convertible with the top down. Without the roof in the way it is much easier to move around and get to frame the subject without parts of the car getting in the way. I always carry with me my Canon G9 so I took it out, set the camera for long exposures (about a second is good) and started snapping away. The resulting images were a bit noisy, but today's noise filtering software make it possible to reduce that sensor noise greatly. I found that shooting while we were driving in a straight line allowed me to keep the cars relatively still while still producing awesome light trails.
