During Quatrocento when artists were developing and focused more on the technical effects a huge debate was going on, if the high detailed technical results was really the result of a skilled artist or just a show off craftsman. Or if a grate art should be rich on its technical aspects, or if grate arts and visionary artists can express themselves on the simpliest manner. And this discussions become a big debate again during impressionism and expressionism, against the salon. And again with cubism, etc, etc.
'The work is the statement!' - Duffy
One of the most successful and famous photographer when he was on the top he burned his negatives and left photography forever. Why? He says that 99.9% of what he was doing was commercial. Therefore rubbish.
"A work of art is the unique result of a unique temperament. Its beauty comes from the fact that the author is what he is. It has nothing to to do with the fact that other people want what they want. Indeed, the moment that an artist takes notice of what other people want, and tries to supply the demand, he ceases to be an artist, and becomes a dull or an amusing craftsman, an honest or a dishonest tradesman."
