The allegory of Plato’s cave is that we view things entirely different through pictures and real life. We can only see so much with our eyes but with photography a whole world is opened up allowing us to create new things and seeing places we have been to. In the reading Susan Sontag speaks about how viewing images changes our perception of the world, the more images we take in the more our ideas change. Photography allows us to create a library  in our head of what we think the world is.
