I checked it out based on your post. It is actually called Dark Light: The Art of Blind Photographers. I watched it on AppleTV via the HBO Go app.
$1.
That aside it still might be worth watching. It profiles three blind photographers about their blindness and their reasons for becoming photographers. There are short interludes with so-called expert photographers from famous publications who basically say "I can't imagine how someone who is blind could take good photographs."
Mostly it is just people talking so in the interviews there is not much happening visually and their individual stories are engaging. Obviously you would miss out on seeing the photographs themselves. Each artist has a very different style and subject matter. The two most straightforward are the underwater photographer (his photos are of fish and the coral reef) and the photographer from New Orleans (his photos are of the people of New Orleans and their eccentric, flamboyant clothes). The last photographer's work was the one I personally responded to the most. Very beautiful photos that are hard to describe, but he actually does a good job describing what they look like. One in particular is a woman silhouetted by different colors of light. He takes a timelapse photo and then shines a flashlight on parts of the woman. The affect makes it look like he painted her, but used light as a brushstroke.
