Conventions of genre (film language)

First of all there is:

Lighting & Colour
The lighting in a scene helps to express the mood and atmosphere that we are experiencing. The audience's attention can be grabbed by brightly lighting an object or gesture that is very important to the story line that we are following whilst keeping other details in either complete darkness or relative. A director can also use shadows to build up suspense and the tension by keeping elements in the scene from the audience.

In a studio the lighting comes from three main sources such as:
Key light- it is the most brightest light and makes the most difference.
The back light- this type of light makes a character/object look more 'rounded'.
The filler light- this light fills in the gaps and softens the hard shadows that the use of key and back lights create. There could be several filler lights used in a studio.

Lighting can be directed from different angles and heights to create different effects, such as:
Underlighting- this type of lighting is when the source light comes from beneath the object. This creates a distorting effect on the character or object and is often used in horror films.
Top lighting- this is when the main source of lighting comes from above the, highlighting the features and facial expressions of a character. It can also be used to make a character look glamorous.
Back lighting- this lighting comes from behind the subject. This type creates a silhouette, if little or no other lightings are used.      

The director of a film is the person who is responsible for the lighting within. They have to manipulate the studio lighting format to achieve the atmosphere that they are trying to convey.
Low-key lighting- this is achieved when only the key and back lights are used. It will then produce a sharp contrast of light and also dark areas on the screen as shadows are created. This effect that is formed is known as chiaroscuro. This is italian words for light (chiaro) and dark (oscuro).
High-key lighting- this is when several filler lights are used. This is lighting that appears normal and realistic to our eyes as the audience; shadows will also appear in this type of lighting.
