The thousand plus years between the division of the Roman Empire into Eastern and Western empires around the 4th century AD and the beginnings of the Renaissance in Europe are known as the medieval period. The era encompasses many artistic styles and periods, including early Christian and Byzantine, Anglo-Saxon and Viking, Insular, Carolingian, Ottonian, Romanesque, and Gothic. During the medieval period, the various secular arts were unified by the Christian church and the sacred arts associated with it.
Lecture & Vocabulary
Exposure: the amount of light that enters the lens and strikes the film or sensor. Exposures are broken down into aperture, which is the diameter of the opening of the lens, and shutter speed, which is the amount of time the light strikes the film. Thus, exposure is a combination of the intensity and duration of light.
Auto exposure: a method of exposure where aperture and shutter speed settings are first read, then set, by the camera's exposure system. Various auto exposure modes allow for customization or biasing the readings.
Correct exposure: the combination of aperture and shutter speed that yields a full-toned negative or slide that yields the best possible tonal representation of the scene onto film or sensor.
Overexposure: in exposure, when too much lighting strikes the film for a proper rendition of the scene.
Underexposure: failure to expose correctly because not enough light has struck the film or sensor to faithfully render the color and brightness values. Underexposed pictures are dark; the more the underexposure the darker they become.
Brightness: the luminance of objects. The brightness of any area of the subject is dependent on how much light falls on it and how reflective it is. Brightness range is the relationship we perceive between the light and dark subjects in a scene.
