For most of history, visual art was grounded in the attempt to reproduce visible reality. That notion got a little sideways in the 19th century, when artists started to explore the idea that their perceptions, emotions, and ideas were also amenable to visual art. By the early 20th century a lot of artists simply tossed representational art out the window.
Art became abstract. Reality got cold-cocked. Smartphones allow us — maybe even encourage us — to isolate sections of reality. To remove those sections from the larger context of reality. To see beauty that exists independent of reality.
