I had the pleasure of seeing this in person at an exhibition at the Brooklyn Museum of Art in 2009. Most of the images of this painting on the internet, including the museum’s website, are too dark and oversaturated. The one I’m linking to is not bad, though I’ve taken the liberty of lightening is slightly. There is another here on Flickr.
Several of Caillebotte’s works are subtitled with the word “effect” — as in Rooftop View (Effect of snow). Like the other French Impressionists, Caillebotte was concerned with the effects of light and atmosphere under different conditions.
Here, he gives us a perfect evocation of the light and atmosphere of a light rain on a small stream. The Yerres River is a tributary of the Seine, southeast of Paris, near where the artist lived.
