Research on Vertigo

Vertigo by Hitchcock

close up of woman's face, introduces a character, makes it intense.
then moves to an extreme close up of different parts of her face, starting with lips, then moving to eyes, builds suspense
zooms in even closer to one eye, and eye opens wide suddenly implying fear.
as the camera zooms in, strange shapes appear, rounded shapes with black holes in the middle, spinning out and getting larger creating the effect that they are spinning out from the eye and coming towards the viewer. as the background becomes black it gives a sense of falling into darkness, making you feel dizzy - linked to the feeling of vertigo.
the shapes come from the characters eyes and shrink back into her eye towards the end, giving the idea that it is something going on inside her head, maybe implying that her mind is confused, perhaps slightly crazy.
