As if it were a painting. As if it were the original.

What is reality?

Reality is reality, isn’t it?


The fact that reality is always subjective and depends on what someone considers important is crucial to understanding what reality is. Objectivity cannot be expected in this context. So it’s no surprise that we talk about “fake news” today—news that we all constantly produce, since we always reflect only refect what is important to us.


The problems that arise from this are familiar to us today. As far back as 400 B.C.—Plato drew attention to this in his "Allegory of the Cave".


It is therefore no surprise that the photorealist painters since the 1960s in the U.S. have used their works to reflect their reality and what is important to them: They portray their friends (Phil, 1969, by Chuck Close); they depict “their” city, New York, as free and multicultural (Lunch Special, 2001, by Richard Estes); and accordingly, they present what matters to them in the right light, such as the diner as a central gathering place (the Richmond Diner, 1983, by Ralph Goings; see photo).


Only more recently have doubts begun to cast a shadow over this glory, and the darker sides of our needs and perspectives have come into sharper focus. The art scene, too, is becoming more diverse and varied. For example, Alexandra Klimas, with her portrait of a bull (Rudi the Unseen Bull, 2025), gives the animal a face and a name.


As a result, the steak probably doesn’t taste quite as good to some people anymore.
