Technical
The relationship between light, the recording medium used to capture the work and the medium used to present the work.
Ethical
Moral and ethical responsibilities that the producer, the subject, and the viewer have of the work.
Cultural
An analysis of the symbols used in the work to convey social meaning at a certain time.
Critical
