First, we hear of a colour-blind photographer who became famous.
Now, we hear of a blind photographer!
Well, one thing about photography is that it captures and expresses the photographer's point of view.
Since these people have a very different point of view from the majority of people, this leads them to capture very different photos from the majority.
They may be able to capture something that a person with normal vision can never see.
Being different has its advantages sometimes.
You can create different things and this novelty sometimes attracts people.
