We live in a culture dominated by pixels, increasingly unmoored from corpor-eal reality. Movies are stuffed with CGI and, in such "performance animation" films as "Beowulf," overwhelmed by them. Some big pop-music hits are so cyberized the singer might as well be telling you to press 1 if you know your party's exten-sion. Even sculpture has adopted digital "rapid prototyping" technology that allows whatever a programmer can imagine to be translated into 3-D objects in plastic. Why should photography be any different? Why shouldn't it give in to the digital temptation to make every landscape shot look like the most absolutely beautiful scenery in the whole history of the universe, or turn every urban view into a high-rise fantasy?
