I saw this on The Oprah show last week. I think if you go to www.oprah.com it might have info. It was on the "Nate builds a dreamhouse" episode. He had a lovely black and white blown upm and I thought he said it was a canvas.
You are definitely going to be happy with my suggestion i.e http://www.canvasmyphoto.com/ as the artists here are professionals and create beautiful photos on canvas and canvas photo prints.
