From carefully considered source to skilled manipulation, no single factor determines photographic success above the quality of the lighting. Luminosity, texture, tone and mood all depend on it without question. But you already knew that, right? If you like your photography brightly seasoned with a splash of unpredictability, then far from pure fundamental, your light source also offers fantastic creative opportunity in subject matter itself. Not to mention an excuse to run around with a torch. There’s that. In fact, flashlight, fibre optics, LEDs, steel wool…. the art of light painting puts an array of tools in experimental reach. It’s novel, it’s fun, and it puts you firmly in charge. We’ve compiled 21 images from high ground to fiery underground displays, showcasing the very best of the lively technique.
