Artist of new medium in landscape painting history

What a fascinating topic! Here are some artists who have made significant contributions to the development of new mediums in landscape painting history:

1. J.M.W. Turner (1775-1851): Known for his innovative use of light and color, Turner was a pioneer of Impressionism and the precursor to Abstract Expressionism. He experimented with oil paints, using thin glazes and bold brushstrokes to capture the fleeting effects of light.
2. Claude Monet (1840-1926): A founder of Impressionism, Monet was a master of capturing the fleeting effects of light and color in his landscapes. He developed a technique called "wet-on-wet," applying layers of paint to canvas without waiting for the previous layer to dry.
3. Pierre-Auguste Renoir (1841-1919): Another Impressionist painter, Renoir was known for his vibrant, expressive use of color. He often used a technique called "alla prima," applying paint to canvas in a single session, without waiting for it to dry.
4. Wassily Kandinsky (1866-1944): A Russian painter and theorist, Kandinsky is credited with creating the first purely abstract landscapes. He believed that colors and shapes could evoke emotions and spiritual experiences, and his paintings often featured geometric forms and vibrant colors.
5. Mark Rothko (1903-1970): An American painter, Rothko is famous for his abstract, rectangular compositions that evoke emotions and spiritual experiences. His landscapes often feature bold, rectangular forms and subtle color gradations.
6. Gerhard Richter (b. 1932): A German painter, Richter is known for his photorealistic landscapes, which often feature blurred or abstracted images. He has also experimented with digital painting and collage techniques.
7. Richard Diebenkorn (1922-1993): An American painter, Diebenkorn is famous for his "Ocean Park" series, which features abstracted, geometric landscapes inspired by the California coast. He often used a technique called "scumbling," applying paint to canvas in a textured, impasto manner.
8. Ellsworth Kelly (1923-2015): An American painter and sculptor, Kelly is known for his geometric, abstract landscapes that often feature bold, flat colors and simple shapes. He has also experimented with digital painting and collage techniques.
9. Brice Marden (b. 1938): An American painter, Marden is famous for his abstract, monochromatic landscapes that often feature subtle color gradations and textured surfaces. He has also experimented with digital painting and collage techniques.
10. Julie Mehretu (b. 1972): An Ethiopian-American painter, Mehretu is known for her large-scale, abstract landscapes that often feature intricate, layered compositions and vibrant colors. She has also experimented with digital painting and collage techniques.

These artists have all pushed the boundaries of landscape painting, experimenting with new mediums, techniques, and styles to create innovative and thought-provoking works of art.
