A certain type of confusion about the relationship between scientific discoveries and art, leads to a frequently asked question: Is photography an art? The answer is: No. It is a technical, not a creative, skill. Art requires a selective re-creation. A camera cannot perform the basic task of painting: a visual conceptualization, i.e., the creation of a concrete in terms of abstract essentials. The selection of camera angles, lighting or lenses is merely a selection of the means to reproduce various aspects of the given, i.e., of an existing concrete. There is an artistic element in some photographs, which is the result of such selectivity as the photographer can exercise, and some of them can be very beautiful — but the same artistic element (purposeful selectivity) is present in many utilitarian products: in the better kinds of furniture, dress design, automobiles, packaging, etc. The commercial art work in ads (or posters or postage stamps) is frequently done by real artists and has greater esthetic value than many paintings, but utilitarian objects cannot be classified as works of art.
