It started with a question: How can we inspire people to take action on climate change?
The answer: Ask the people of Sydney to turn off their lights for one hour.
On 31 March 2007, 2.2 million people and 2100 Sydney businesses turned off their lights for one hour – Earth Hour. If the greenhouse reduction achieved in the Sydney CBD during Earth Hour was sustained for a year, it would be equivalent to taking 48,616 cars off the road for a year.
It is happening again this year.

Oaky, I changed the date to reflect the North American Earth Hour schedule.
I have realized that in digital camera models, specialized detectors help to aim automatically. The particular sensors involving some surveillance cameras change in contrast, while others use a beam with infra-red (IR) light, specially in low lighting. Higher standards cameras at times use a mixture of both methods and probably have Face Priority AF where the digital camera can ‘See’ the face while keeping focused only in that. Many thanks for sharing your ideas on this website.
