Classical style in film form

Summarise ( with examples form Casablanca and other films where possible ) the key conventions and "rules" of classical Hollywood style film form.

Cinematography and lighting

( e.g matching eyelines, 180 degree rule , framing and shot types  for clear narrative   )

Matching eyelines - when the camera shows a person looking at another person at eye level, make the conversation or encounter seem realistic 

180 degree rule - 180-degree rule is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene. This is performed by keeping the camera at an 180 angle, makes the audience feel the film is more real

Framing - a shot that involves a series of frames on one particular thing, such as a conversation, this is a way to keep the viewers engaged

Editing 

( e.g cause and effect, invisible continuity editing , use of shot /reverse shot , narrative resolution should be clear )

Cause and effect - linking the reason for something happening to the outcome, allows viewers to be satisfied and realise what is going on in the narrative

invisible editing - arranging shots in a sequence to suggest a progression of events.

shot/reverse shot - for example i a conversation, this is where the camera pans from person to person to allow the audience to focus on whos talking
