Often materials and techniques used in a piece mean only something to fellow artists. Joseph Albers square paintings are generally dismissed by the public as bad or that their 8 year could paint that. However, they are significant to the art world because of color theory and simultaneous contrast. It is the same with the work of Pollock and the Abstract Expressionists. The same goes for photography, the only people who care about the materials and philosophy behind the image are other artists, curators and art historians.
