what moved monet to paint impression sunrise
Monet has since established his place as one of the true masters of Impressionist art. Impression, Sunrise is lauded as one of the finest examples of Impressionism, exemplifying the movement as a whole through the dreamy, hazy landscape.
When travelling to Paris, Monet noticed other arts students copying pieces from the great masters. He took a different approach, preferring to sit at a window and paint what he saw. His studies were interrupted when he was drafted into the First Regiment of the African Light Cavalry; although his wealthy father had the opportunity to pay for MonetвЂ™s exemption from conscription, he refused to do so after Monet refused to give up painting. After a year of service, Monet contracted typhoid fever and went absent without leave.

Following this name change, the Impressionist movement saw a surge in popularity, with Monet at the forefront. The artist continued to capture “impressions” of his surroundings for the remainder of his life. In 1890 and 1891, he completed a series that explored the effects of light, atmosphere, and seasonal changes on Haystacks; the following few years, he applied the same treatment to a Gothic façade in his Rouen Cathedral series; and, for his most ambitious project, Monet spent 30 years creating 250 large-scale paintings of Water Lilies.
The hazy scene of Impression, Sunrise strayed from traditional landscape painting and classic, idealized beauty. Paul Smith suggested that with this style, Monet meant to express “other beliefs about artistic quality which might be tied to the ideologies being consolidated by the emergent bourgeoisie from which he came.”  Loose brush strokes meant to suggest the scene rather than to mimetically represent it demonstrate the emergent Impressionist movement. In the wake of an emergent industrialization in France, this style expressed innovative individuality. Considering this, Smith claims that “Impression, Sunrise was about Monet’s search for spontaneous expression, but was guided by definite and historically specific ideas about what spontaneous expression was.” 
Although it may seem that the Sun is the brightest spot on the canvas, it is in fact, when measured with a photometer, the same brightness (or luminance) as the sky.  Dr. Margaret Livingstone, a professor of neurobiology at Harvard University, said “If you make a black and white copy of Impression: Sunrise, the Sun disappears [almost] entirely.” 
Modern day reception:
Modern day critics of Monet have leveled the criticism against him that, many of his works were completed days or weeks later away from the motif. Such a style went against everything that the Impressionists claimed to be and towards the end of his career Monet certainly switched to this method of painting.
Despite its hostile contemporary reception, the painting sold instantly and was later gifted to the Musée Marmottan where it currently resides. Despite selling for 800 francs initially, the work has subsequently become a national piece that is beyond price.
In 1877 a series of paintings at St-Lazare Station had Monet looking at smoke and steam and the way that they affected colour and visibility, being sometimes opaque and sometimes translucent. He was to further use this study in the painting of the effects of mist and rain on the landscape.  The study of the effects of atmosphere was to evolve into a number of series of paintings in which Monet repeatedly painted the same subject (such as his water lilies series)  in different lights, at different hours of the day, and through the changes of weather and season. This process began in the 1880s and continued until the end of his life in 1926.
