Fill Lighting

Back Lighting

Back Light:  Backlighting refers to the process of illuminating the subject from the back.
Fill Light:  a fill light  may be used to reduce the contrast of a scene and provide some illumination for the areas of the image that are in shadow.
Key Light: The purpose of the key light is to highlight the form and dimension of the subject.
Hair Light:Used to separate hair from background; 1 to 1.5 stops higher relative to key, so this eliminates reflectors as illumination.
Color Temperature: Color temperature is the characteristic of visible light that has important applications in photography lighting, etc. The temperature is conventionally stated in units of absolute temperature, K. Color temperature is related to Planck's law and to Wien's displacement law.
