He is considered a pioneer of Impressionism, a movement characterized by its focus on capturing fleeting moments and light. The oil painting medium allowed Pissarro to create rich, luminous colors and a sense of movement in his work. He also experimented with other techniques like pointillism and divisionism, using small dots of color to create the illusion of light and form.
While he primarily used oil on canvas, Pissarro occasionally worked with other mediums like watercolor and pastel.
