While a camera shows us the reality, a painting can show us the underlying emotions.
Why do we miss the opportunity of making use of a universal language? Art enables us to communicate across all language boundaries. People who cannot read or write would still be able to understand a realistic painting or a sculpture. However, if artists choose to concentrate on abstracts they may create beautiful colours and shapes but does that tell us anything? Will those pictures still paint a thousand words?
If artists continue to create art for the chosen few they need not wonder that nobody will buy their artworks. Those who can afford it will go for horrendously expensive works by artists which have been declared geniuses by the critics.
Will a work of art become special because there is a scandalous story to be told about the artist or his work? Will a painting only be worth having if the elite agrees on it being unique?
If we go back to the origins of art it was meant to tell a story for everyone to understand. Today ordinary people usually fail to see what they are perhaps meant to see. Does that mean everybody has to attend art classes before they can understand the artwork?
If that was so it would not be my kind of art. By the way there is a lively discussion about the subject on linkedin.
