I signed up to do this earlier this month, and today was the day to capture a picture to contribute. The chance presented itself when Sara and I went on an evening stroll through the neighborhood, and ended up on a playground.
From their website:
On this one single day we ask you to pick up your camera and help us photograph daily life. What is close to you? What matters to you? We will connect your images to images from all around the world, creating a unique online experience where photographs will be shared, compared and explored. Your view on life will be preserved to inspire generations to come.
Our mission is to use the power of photography to create, share and inspire perspectives on daily life – today and tomorrow.
