Just because they can't see, it doesn't mean that blind people can't be artists. Indeed, there's NEBA - the National Exhibits of Blind Artists - an organization dedicated to showcasing the work of artists who are blind or visually impaired.

But can a blind person be a successful photographer? Meet Rosita McKenzie, 56, from Portobello, Scotland. Her photographs are now being showcased in an arts festival in Edinburgh:

Speaking to the BBC Scotland news website she said she never thought she would be able to take photographs.

She said: "This whole process helps me to burn something into my memory, something I can use to recall as images in your head can become less clear.

"People explain to me more about the things that are around me when I have my camera. [...]

"I have had photographers say that I have captured things they would not have been able to for example I took a picture of a bridge of the Edinburgh Canal and in the bottom right hand corner there was half an image of a jogger.

"I can then have the pictures produced into raised drawings."

And yes, she has a digital camera with autofocus: Link
