This document discusses the relationship between painting and nature. It notes that color is an important element in both nature and artwork, with nature providing colorful subjects like flowers, trees, and sea creatures. It also distinguishes between organic shapes commonly seen in nature, like clouds and leaves, and geometric shapes that can be measured, such as circles and triangles. The document highlights two Filipino artists, Bernardo Duldulao and Jose Joya, who are known for paintings depicting nature, with Joya's works being more abstract. It concludes by defining realistic art as depicting subjects as they truly appear, while abstract art shows subjects according to the painter's thoughts and feelings rather than just visual perception.
