Revealing: In the scene where Griet has her left ear pierced in order to wear the earring for the portrait, the cloth covering her hair and ears stops just short of covering a well-healed hole in her already pierced right ear.

Factual error: In the scene where Griet is introduced to the camera obscura, far too much light is projected onto Vermeer's and Griet's faces. Camera obscuras don't make their own light; rather the image produced on the viewing screen is always dull.

Continuity: In the scene where Vermeer picks out earrings for his wife to wear, he selects two pearl earrings (same one later found on Griet). When he hands them to his wife, he gives them both to her, however when you look at Vermeer in the next shot he is holding one of the earrings.
