The opening sequence of 'Dirty Dancing'...
The camera first captures the car from a distance and films it getting closer and then driving past. The camera has such a smooth movement as it pans from left to right.
Here the camera uses a mid shot to introduces the two young female characters. The camera is far enough away to show the audience all they need to see at this point. It also captures their normality as they continue to do everyday things.
The Camera is then used to capture the relationship between a father and daughter. The close up on the pair shows the closeness between the two characters. The car continues to drive, and the music continues to play as the narrater talks over.
The camera is then used to zoom in on a sign that is relevant, to the characters. The camera angle puts the views in the passengers perspective as the car drives along.
I like that way that as the camera gets closer to the sign it zooms right in and it sort of looks like the camera is trying to be part of the characters eyes, because it comes into focus as it gets closer and then becomes out of sight as they pass.
Again a close up is used, as the camera shows only the female character, 'Baby', it shows her importance of her character in the film. She is shown sat in the back seat, with a smile on her face, this helps to set the mood for the next part of the movie.
I believe that the frequent use of close ups is because the characters are in such close proximity, as they are in a car together.
