This series of works is titled Natural Record. Without the use of paints and brushes, the paint comes from the color of the leaves, the brush is the bark, the sunlight is the blending agent, and the works are dried by the sun. For a long time, the works are kept out of sunlight to avoid exposure. The traces of some paintings are the shapes of the bark. It is an attempt to create art without the use of any artificial products, where all the elements are natural and temporary. It is therefore malleable and alive, and the work itself is always breathing and growing.
Collecting plants around BigCi, the artist residency in Australia in which the works were created, Yumo Wu used the water from the leaves and bark of the plant as the pigment, and then used the branches as a brush to print on the paper to form an abstract plant painting or recorded image in a minimal way.
