David Fokos does slow exposures and writes that this reflects an underlying philosophy of how we see the world. Luckily it’s more impressionistic than transcendental:

Using long exposures ranging from 20 seconds up to 60 minutes, I have tried to filter out what I call the “visual noise” of everyday life in order to reveal the fundamental, underlying forms of our world — it is these forms that I think we respond to on a visceral level. My long time exposures average out all the short-term, temporal events — the visual noise — within a scene.
