You are exactly right! They project a photograph onto their surface and copy it exactly. I am not impressed.
Oh, it still takes plenty of skill. David Hockney wrote a book ("Secret Knowledge") about classical artists using a type of projection even back in the Renaissance. He was convinced Vermeer used a method of projection in several of his paintings.
I was just pointing out that there's really nothing new here. The article sounded like this was some new development, or something.

There are companies advertizing in art magazines that they will take your photos and print them on canvas so you can paint over them.
