In film studies a specific vocabulary has been created
in order to converse in words the visual 'language' of movies.
the visuals of a film do have a language of sorts, they tell
stories with images and the elements of the 'vocabulary' can
be found in its construction, the way the images are composed
or edited together. Unconsciously we all have learned the
basics of this 'language' whether we are aware of it or not.
We can often understand the narrative of a movie even with
the sound off.
For exanple, the close-up shot at left of Sharmila Tagore
looking off camera. We know she is looking at something. Logically
the next shot in the film would be what she is looking at.
We would be shown this and know from our understanding of
film language that the next shot should be what she is 'seeing'.
In film studies this is called a 'Point of View' shot.
It is called this because what the camera is showing is telling
the audience that what they are seeing is as if coming from
the eyes or point of view of the character.
