Time-lapse movies of dawn and dusk in San Francisco; post-processing used to add a 'tilt-shift' effect to some of the sequences.

Inspiration drawn from Keith Loutit and his series of amazing time-lapsed, tilt-shifted videos of Sydney: vimeo.com/keithloutit/
..and I shouldn't forget to mention the idea of using an SLR for video from Reverie: vincentlaforet.com/

Equipment:
- Canon EOS 450D (Rebel XSi)
- Netbook (Aspire One) running Mandriva 2009
- gphoto 2.4.3 - command line:
gphoto2 --set-config capture=on --capture-image-and-download -I 5
- dodgy tripod that shook like crazy in the wind
