What were the major innovations of the impressionists in painting style and subject matter PLEASE HELP ME

-Impressionism got its start when several painters began using more natural methods of lighting their work and looking at the world with freshness and immediacy.

-Their paintings were refused by the official Salon. Because they have certain aims in common, they band together to exhibit, often in a photographer’s Paris studio.

-An Impressionist paints landscapes and outdoor scenes outside, often working for a very short period of time.

-Although French painters earlier in the century had also confronted a landscape directly, as had the English painter Constable in some of his smaller oil paintings, these artists used more conventional (and therefore acceptable) colors.

Hope this helps:)
