Exposure and tone mapping
- [Instructor] Exposure and tone mapping are the methods whereby we bring the range of all possible brightnesses into a realm that can be reproduced in traditional media. When you go to a movie and you see a daylight shot on the screen, the projection in the theater is not nearly as bright as the actual daylight represented in that shot. Currently media cannot reproduce the full dynamic range of real-world lighting. For display, we must constrain the dynamic range into the gamut of the display medium. And additionally, standard cameras can't capture the full range at the same time. When you shoot with an ordinary camera like a digital SLR, you have to expose for the highlights or the shadows because you can't do them both at once. Camera exposure of course refers to exposing the sensor or film inside the camera to light and you can set the exposure to determine how much light is entering the camera and thereby set which tones are captured. The same rules apply to a photometric 3D…
