Lilianna: it is not an either or issue, the thrust of these articles is that photography IS being changed by smartphones. Their ubiquity and connectivity means that it is very unlikely any event will not be documented in some fashion.It may not be high art, we may not like the subject matter, but they are being used and used sometimes to great effect.
Well they could be used for Hi-Art. In my, well now unfortunately inactive art career, I often found myself to be the most creative when being extremely limited by equipment or other parameters regarding a particular project. At least to me art is about an idea as it is about execution, especially when execution is limited by circumstance. I photographed a wedding this summer, and during the ceremony a lot of people had a cellphone up recording what was going on. I wonder what that does to us and how we experience the world. When I was in Budapest, I walked around for a day without a camera first, before going out again and photographing it. I found putting the camera down sometimes to be refreshing after years of photographing. I think that it can separate you from experience, and that it is also funny when I see something and think how stupid it was to leave the camera at home :)
