Basically you take a photograph everyday. Then keep them in chronological order. I did this for one semester and it opened my eyes to a different way of viewing pictures. I no longer take a photo everyday but I have taken over 10,000 pictures this year. This is the book I created called Ordinary. I did this for a class assignment.http://www.blurb.com/bookstore/detail/649297
