Please whats this movie?

it's about a woman who has no love life and is dedicated to her work as a painting restorer. which basically restore old paintings to give off brighter colour. well she comes across a painting that has a face missing so she has to construct it from scratch. she then falls in love with this guy and she uses his face as the one in the painting. thats all i really know, she may teach some lessons on art history i'm not sure.
