One of my favourite works from Claude Monet - cliff walk at pourville. The built up paint, attention to detail, wind blowing against the female subjects. It's all very breathtaking and luminous.

Claude Monet, La Gare Saint-Lazare, 1877, oil on canvas, 75 x 104 cm (Musée d'Orsay, Paris) "In their landscapes and genre scenes, the Impressionist tried to arrest a particular moment in time by pinpointing specific atmospheric conditions—light flickering on water, moving clouds, a burst of rain. Their technique tried to capture what they saw. They painted small commas of pure color one next to another. When viewer stood at a reasonable distance their eyes would see a mix of individual marks; colors that had blended optically. This method created more vibrant colors than colors mixed as physical paint on a palette. "(Khan Academy)
