In order to pass through the giant portrait of Lady Dimitrescu in the Atelier, you’ll need to “Let the 5 bells of this chamber ring out.” To do this, you must shoot the 5 bells in this room. The locations of the bells are as follows:
- To the left of the painting of the angels holding the 5 bells
- On a pendulum in the wall swinging back and forth by the gears
- On a case across from the angel painting
- On top of the chandelier
- Climb up the stairs and look out the window to find the last bell outside
Shoot all the bells to open the hidden door and proceed to the Attic.
