Illumination - Policy

The illumination refers to the type of lighting both structurally and the range of time when the frame is illuminated. Illumination encompasses both sunlight and artificial lighting. The illumination start and end time indicate the hour/minutes/seconds when a frame is illuminated. While the illumination type name indicates if it is naturally, artificially, or both illuminated.

All frames must include the hours of illumination from start to finish in a 24-hour clock and indicate the type of illumination on the frame. The goal is to understand the different types of illuminations as well as the times in which frames can be seen by audiences passing by.

Standard Illumination Types:

There are four types of illuminations. Each one refers to a specific type of lighting that allows for the frame and subsequently the face to be seen.

Use Cases:

There are multiple ways a frame can be illuminated. If a frame is non-digital and has light features as illustrated in the first example below then this location has both artificial and natural lighting. The media operator will then need to indicate the hours of illumination which will include a start time and an end time. As well as the illumination type which in this case would be frontlit.

Below are several examples of the type of illumination available to media operators.
