Over the last four years, Finnish light photographer Janne Parviainen has created a series of light paintings using only a camera and LED torches. There is no post-processing used in the creation of his images. Parviainen simply calculates his settings, opens the shutter, and then spends "a few seconds to hours, depending," tracing a room with his LED to create images straight from the camera lens. The results are both extraordinary and slightly ghostly. [Photo/icpress.cn]
