That is a lot of shadow and highlight detail thrown into the mix. Frank Filippone red735i@earthlink.net Yamada showed a 177x144 pixel image sensor that takes three photos of the same scene in rapid succession. In one example, he said, the first exposure lasts 1.5 microseconds, the second 150 microseconds, and the third 15,000 microseconds (not far from a 1/60 second exposure). Extra circuitry built into the sensor records the data from the multiple exposures and uses an assortment of electronic capacitors to combine it into a single image that spans a greater dynamic range.
