In the book The Blind Photographer, Bavcar who is a philosopher, compiled 150 pictures made from photographers without eyesight.
This project was particularly interesting because it introduce aspects of photography that most photographers lack. The blind shows us "truths that the that we the sighted have forgotten to see."
It is interesting to see how the blind use photography to show the world we all live in, but perceive differently. The technical choices they made are curiously accurate, and really makes the viewer think what does a blind person really "see"?
