Ambient light means the light that is already present in a scene, before any additional lighting is added. It usually refers to natural light, either outdoors or coming through windows etc. It can also mean artificial lights such as normal room lights. This is vital for my trailer as the thriller genre needs to create a uneasy atmosphere therefore darkness will be used and therefore we will use minimal lighting. However in scenes that take place in the equilibrium of the narrative the lighting will be what would usually be used in a family atmosphere at dinner time, therefore the use of spotlights would be used. Furthermore the use of of a chandelier type light fitting is used above the table.
