I screwed some ND filters to my lens and slowed down the shutter speed to take long exposure photos during the daytime in continuous shot mode, and turned those image sequences into video clips, which I've compiled together to make this.
I'm a bit disappointed with the way it turned out. As the original aim was to achieve a slightly sinister ephemeral atmosphere around London, like a ghost-town. However, I didn't realize that lots of people don't move very much! Also, as I ranged the shutter speed between 2 and 6 secs [depending on the location], this meant that the original video clips were rather choppy, so I had to speed them up, making the resulting footage look more like a generic sped up video.
I'm going to try again at some point with another ND8 filter screwed on the lens for longer shutter speeds, and pick locations where no one stands still to give a proper ghost effect.
Locations the clips were taken [in order of appearance in the video]: Marble Arch, Oxford Street, Oxford Circus, Piccadilly Circus, China Town, Covent Garden, British Museum, Trafalgar Square, St Paul's Cathedral, Millennium Bridge.
I made the music for the video using some virtual string instruments controlled by my electric piano.
