The Chicago Art Institute has released a video showing how conservator Faye Wrubel restored Caillebotte's masterpiece:
The striking results of the restoration reveals greater saturation of color, sharper edges, and more contrast with an overall effect of more visual depth. Overpainting was removed from the once yellow sky, exposing a bluer surface with gradation indicating light and movement.
“What we have been seeing all these years may have been beautiful, we may have all loved it, but it wasn’t right,” Wrubel said of the findings’ impact.
In addition to visible details that were brought to light, conservators uncovered new information about the masterpiece by comparing the ultraviolet and x-ray images to a preparatory sketch for the painting as well as study residing at Paris’ Musée Marmottan.
