Join Aaron F. Ross for an in-depth discussion in this video Exposure and tone mapping, part of 3ds Max: Advanced Lighting.
- [Narrator] 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 censor…or film inside the camera to light.…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 rendering.…Here is a composite render showing three different exposures…
