UK-based photographer Ian Hobson is an expert at all kinds of impressive light art photography. When you first see his images, a collection called Waving Torches at Things, you won’t believe that he creates them directly from his camera without the use of any digital manipulation. But, according to his website, he says, “All images are photographs, straight from the camera. Nothing is added, the only post-processing is conversion of the digital negatives into jpegs.”
