I first saw paintings by Corot when I was still a student in London. The silver light and lightness of touch always make an impression on me. More recently I have been looking at his drawings. Here are a couple...a lesson in economy of means (but what scale they have!):
Sketch book (1857), landscape with tall trees with a horseman, a figure reading amidst trees and a sketch of a head.
Landscape with a figure near a tree, pen & brown ink, 20.6x16cm, circa 1852.
