The Contrast is Limited

Monday, April 9. 2001


The contrast of the image is typically limited to 2 orders of magnitude. This causes two problems: intensities on the picture and in the image do not match, and the large dynamic range of intensities of some scenes has to be contracted. Photo exposure, CG tone mapping, photo processing, lighting, addition of flare and halo, etc.
