Olson's company is called 3D Photoworks. It produces copies of artwork in three dimensions: height, width and depth. Olson says this is how the process works. First, a painting is scanned, and a 3D computer image is created. Then it is sent to a machine that digitally sculpts it. Then the original image is printed on top of the relief. The whole process can take up to four weeks. Olson says that creating art in this way gives a blind person a new experience. “When a blind person can interact with art and create their own opinions, it’s freedom to them. It represents freedom, independence. People tell us it's a basic civil right. Nihal Erkan lost her eyesight completely when she was 6 years old.
