Final answer:
Claude Monet's Rouen Cathedral series exemplifies his Impressionist approach to observing the effects of light and atmosphere on the appearance of a subject, a technique he applied to various series including haystacks and waterlilies.
Step-by-step explanation:
Claude Monet, a central figure in the Impressionist movement, is renowned for his series of paintings which explore the effects of light and atmosphere on color. In particular, his Rouen Cathedral series demonstrates his fascination with light, showing the cathedral at various times of the day and in different conditions. By painting over 30 views of the cathedral, Monet rented a room across from the edifice and captured the nuances of changing light on its facade, a method he applied to other subjects such as haystacks and waterlilies.
His haystacks series exhibits similar interests and was significant as Monet's first series exhibited. The haystacks near his home in Giverny provided the perfect subject to document the nuanced effects of sunlight and season, as seen in works like Haystacks (Effect of Snow and Sun) and Haystacks Midday. Away from his native France, Monet's works on Venice, particularly the Grand Canal, showcase the altering appearance of the location under different light conditions.
