You're very intent on whether they are innovating or not but I don't think innovation is what makes an artist an artist. Inventing HDR or Instagram doesn't make that person an artist, but if they do something really good with it, then they are an artist and an innovator.

Like Michael Kenna or Moersch shooting with a Holga - it isn't art because they are the first ones to do it, it's art because they are so good that they can take a very simple fallible tool and make something beautiful.
