Light Painting with Automobile Lights
During the Spring Semester of 2013, I had the opportunity to experiment with abstract light painting photography as part of a Photo 312 class at Sacramento City College. Light painting, also known as light drawing, is a creative technique where exposures are created by moving a light source, moving the camera, or manipulating optics during a long exposure. Rather than simply using a stationary tripod to track traffic, I wanted to explore an entirely different perspective on how city illumination can be rendered on a camera sensor.
I set up my camera on the west end of the iconic Sacramento Tower Bridge just after dark, framing the oncoming evening traffic. Focusing directly on the headlamps of vehicles driving toward me, I quickly adjusted the manual focus ring while simultaneously depressing the shutter button. This rapid racking of the focal plane transformed ordinary automotive headlights into an expressive, energetic composition.
Instead of clean, uniform light streaks, the resulting frame captures vibrant, squiggly lines of illumination that appear to be jetting directly out toward the viewer. The intentional defocusing bends the photons across the sensor, creating an illusion of depth, kinetic speed, and raw electrical motion.
Creating this style of abstract light painting photography served both artistic and educational purposes. It pushed me beyond conventional rules of tack-sharp focus and allowed me to treat urban motion as an abstract canvas. Photography often thrives when we break routine habits and let light guide the visual narrative. By twisting the focus ring mid-exposure, a familiar Sacramento bridge transit corridor was instantly re-imagined as a vivid explosion of color, geometry, and pure nighttime energy.
