Vertigo opening credits

The extreme close up of the woman's face in black and white suggests hidden identity and not showing the whole picture. The panning upwards reveals more of her face and uncovers her character more. The extreme close up of her eyes darting around shows her anxiety and uncertainty, when the screen turns red and the music deepens creating tension and a sense of danger, her eye widens suggesting she is seeing something unpleasant. The swirls inside her eye take over the screen and seem hypnotic and connotes the swirls are going deeper and deeper into her thoughts.
