earth hour

2,712 cities, towns and municipalities in 83 countries have already committed to VOTE EARTH for Earth Hour 2009, as part of the worlds first global election between Earth and global warming.


One way to individually participate is by creating your own light graffiti. Writing in light. And it will enable you to take some memorable photos during Earth Hour.

Here’s how:

  1. You’ll need: a camera, a tripod (or a flat, stable surface), and a light source (torch, bike lamp, etc). Any colour of light source should work. To be really sustainable, you could use one of WWF’s wind-up torches.
  2. Set your camera to ‘manual’ mode (available on all SLR cameras and most compact cameras). This will allow you to set the exposure and aperture manually.
  3. Set the exposure anywhere between 10 and 20 seconds. The amount really depends on how much you want to write and how much background you want to show. Remember, experimenting is the key!
  4. Set the aperture to 8. Once again, this is by no means the ‘correct’ setting. Try any number of variations and see how the effect changes.
  5. When the camera is attached to a tripod (or on a flat surface) get a friend to push the button (or set to the self-timer mode) and get writing!
