Adobe color scientist Bruce Fraser describes the differences between film and digital exposure better than I was able to for Dilberta (who came for a visit last weekend!) While film, and our own photodetectors - retnas, apply a compensating curve to evenly distribute many levels of brightness over a linear perception field, silicon based photodetectors compress the shadows and expand highlights. Linearization must be done, after the exposure, with software. Fraser explains it all, and what to do to get better digital exposure, in this Adobe Whitepaper.

[Thanks to Rich H for the pointer.]
