"The Gherkin" and some other buildings in London's business district. This was definitely a 10 second exposure... as these buildings had very poor lighting on them that night.
We don’t make art to show someone what something looks like. All this requires is eyes (or a lens). Art is supposed to have meaning, emotion, power, or magic. Alan & Mario "FourThirds"
