picture literacy

We see pictures around us, newspaper,magazine, ads, or even a short moment of view of one thing. Someone may press the shutter to catch the moment. A picture can mean one thing or more, a series of picture can tell a powerful story. The charm of the picture is a second of shoot, the next second may change the story completely. Picture tells stories to people, and people find stories and catch the moment by camera. Moreover, the story defination could change by different people's view. That is how picture be a literacy and creat in human civilazation.
One picture seen by some people may take just a picture. Others may find the story behind, or even add their own story into the picture. Literacy is a product of human creativity. A catch of moment may not be copy in any forms, cause the typical moment would never appear again, even how much people trying to rebuild the specific "second".
This is how picture story unique. Like the classic book publish on centuries ago. The author is not exist anymore, and people still reading his work. Even their are any person who may be better than him, but never find the author's think on that time of writing. Picture also record the history and tell stories to people around or even next generation.
