Factual error: When 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.
Girl with a Pearl Earring (2003)
1 factual error
Directed by: Peter Webber
Starring: Colin Firth, Scarlett Johansson, Tom Wilkinson, Cillian Murphy, Judy Parfitt
Continuity mistake: When 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.
Answer: Obviously, since she married him in the end.
