Painting outdoors in natural light (plein air)
Plein air is a French phrase for "open air". It means painting outside, not in a studio. In the 1800s metal paint tubes made this easy to carry. Artists such as Claude Monet painted fields, rivers and haystacks.
Outdoors, light changes: morning is warm and soft, noon is bright with short shadows, evening is orange. A plein air painter must work fast and catch the feeling of the moment. In the 3D, move the sun and see how the canvas colour changes.
Nature photography as art
When photography became popular, some artists used cameras instead of brushes. A good nature photograph is not a copy. The photographer chooses the frame (what to include and cut), the light, the moment and the angle. In the 3D, three frames on the same landscape give three different pictures.
Photographers such as Ansel Adams made black-and-white images of mountain parks and also helped people care about protecting them.
Land Art and environmental art
Land Art (also called Earth Art or environmental art) is art made in the landscape, with the landscape. The place is not only the background; it is the material and part of the meaning.
- Robert Smithson’s Spiral Jetty (1970) is a spiral of rock and earth in a salt lake in Utah, USA.
- Richard Long walks in a line and makes stone circles and lines on his path.
- Andy Goldsworthy builds with leaves, ice, stones and twigs, and lets weather change them.
Many such works are temporary: waves, wind or snow take them away. A photo is often kept as a record. This teaches us that nature is always changing. Stone piles, rangoli with flower petals and village mud art are close ideas in India.
Art, ecological awareness and sustainable practice
Eco art has two jobs.
- Raise awareness: an artwork can show polluted rivers, melting ice or lost forests so that people feel the problem.
- Be sustainable: the way the artwork is made should also be kind to nature.
Sustainable art practice means: reuse waste (bottles, cloth, metal scraps), use natural or non-toxic colours, avoid single-use plastic, make works that can be taken apart and recycled, and share tools. Nek Chand’s Rock Garden in Chandigarh, India, is made from waste; the artist El Anatsui makes huge wall hangings from bottle tops.
Honest question for every artist: does my art itself leave litter?
Key formulas and definitions
- Plein air = painting outdoors, in natural light
- Frame = the part of the view the photographer chooses
- Land Art = art made in and with the landscape
- Eco art = art that raises awareness or uses sustainable ways
- Reuse + Reduce + Recycle = three habits of sustainable art
Worked examples
1. A painter finishes a sky study at 8 a.m. and wants to match the same light at the same place. At what time of day should she come back tomorrow?
At about the same time, 8 a.m., because the light and shadows change through the day and repeat at similar times.
2. A Land Art spiral uses 24 stones. Waves wash away 6 of them. How many stones are left, and what percent was lost?
24 − 6 = 18 stones left. Lost = 6 ÷ 24 × 100 = 25%.
3. A class collects 36 plastic bottles and uses 9 bottles in each small sculpture. How many sculptures can they make?
36 ÷ 9 = 4 sculptures. This is reuse: the bottles become art instead of litter.
Common mistakes
- Thinking plein air means painting from a photo. It means painting on site, in front of the view.
- Thinking a nature photo is just a copy of nature. The framing and light are art decisions.
- Thinking Land Art must last forever. Many works are made to change or disappear.
- Thinking eco art is only art about nature. The materials and the process should also be kind to nature.
