QUALITATIVE AND QUANTITATIVE RESULTS |
EXPOSURE CONTROLS
The settings of the computer screen can have a significant impact on one’s perception of the lighting levels in a computer-generated daylight simulation model. Improper brightness, contrast and ambient default setup in the display option of the computer simulation program add to the inaccuracies in illumination when rendered.
Compare the dynamic range of a real scene (luminance ratio on the order of 10000:1) to maximum dynamic range of most monitors (100:1). Thus, it is hard to achieve the full dynamic range with the present day monitors. The false color image representation in computers overcomes limitations in the dynamic range of displays to an extent by replacing tone mapping with a numerical legend [1].
