House Near Orléansby Jean-Baptiste-Camille Corot, ca. 1830, oil on paper mounted on millboard, 11¼ x 153⁄16. Collection J. Paul Getty Museum, Los Angeles, California.
This painting is featured in the Quick Sketches blog.
I interviewed professor Frank Wright for Workshop magazine and he made the point that Corot was not the kind of plein air painter who work for 2-3 hours and then considered the painting finished. Instead, he went back to the same location at the same time of day and developed his paintings over weeks. I think this landscape was developed that way because the subject is carefully studied, composed, and executed.
I get that too... it's a bit haunting. I like it a lot.
