A Street in Ravenna by Signorini

The street is half in shadow and half in light, with an irregular shadow edge cast from the building tops across the cobblestones. 

A Street in Ravenna by Telemaco Signorini (1835-1901).
To pull off the idea, Signorini must have been very conscious of grouping the values. The tones in the illuminated side of the street are well organized as a single light shape. And the values of all the forms in shadow never go above a middle range. The sky is kept fairly flat, and he didn't overplay the warm and cool effects.
